Apple Mail Virus?
I use Apple Mail in conjunction with 3 separate Email accounts. My iMap and Google accounts work fine, but my Hotmail account is behaving very strangely. When I view an Email in Hotmail it looks fine, but recently when viewed in Apple Mail all Emails to my Hotmail account are addressed to [email protected] I don't have an account with firstrade whoever they might be and nor do I have their details in my address book.
Can anyone shed any light on what might be the cause of this...is this a virus of some sort?
I have found an answer to the problem on a different thread....follow the link below

Apple Mail, IMAP messages are mangled
I have just connected to my IMAP account with Apple Mail. It appears that there is an encoding problem. (It was using Outlook for Mac before because of work obligations, but I'd really prefer to use Apple Mail.) These messages still look okay in the message view of the IMAP account through Outlook for Mac (2011 v14.2.3), but all the messages seem to mangled as far as Webmail (Roundcube) or Apple Mail (v5.2) are concerned.
I can't find any IMAP setting options in stupid Microsoft Outlook for Mac. Does anyone know if there's one in Apple Mail that might allow me to use these emails? I'm happy to provide more info, it's really bugging me.
All my messages look like this (source below as well):

<Emails Edited By Host>There is something wrong there all right. I am having the same problem.
In my home imac, I leave Mail open when I leave for work. During the day I may access gmail via the web interface, read and/or delete some e-mails, that sort of quite normal things. When I come home, Mail in the iMac has not detected any of the changes.
This used to work with Tiger without any problems, Mail simply saw all the changes as one would expect. Definite regression, and it would be nice to have it fixed somehow... -
How can I disable the Spam filter on Apple Mail?
Hi All!
About a year ago I installed Virus Barrier X6 with Personal Antispam on my 27 inch iMac. The Virus software seems great and I have no issues. The Antispam I have never installed and i have continued with the Junk options, however I have an issue with what I think is the Intego version (you may correct me) which is driving me mad!
On the left hand column of my Apple mail software is a folder headed 'ON MY MAC', called Spam. eBay messages, work messages, banking etc etc are going straight into there and I cannot seem to alter any settings.
The email is highlighted in purple and when I try right clicking, it offers only the standard options as with any other email. There are no spam options at the top of the screen, there is nothing on the Launchpad relating to it and when I search the mac (top right), there are absolutely no hits whatsoever entitled Spam or similar?
Since my recent update to M/Lion, the Intego Personal Antispam icon on Launchpad has disappeared by the way - so I cannot be sure that this is an Intego. Is it possibly an Apple generated icon?
I would be happy to keep it there if I could control it. If not, I just need rid of the thing. I cannot teach the software to learn or unlearn - so i am completely at its mercy. Your help would be very much appreciated.
Thank you in anticipation, John.
A screen shot is at this link for clarification.
ImageShack® - Online Photo and Video HostingIt is caused by a rule within Apple Mail. Check Preference > Rules.
If Personal Antispam has disappeared, it's because the product was discountinued. See this link for that info plus some instructions on how to deal with what you are seeing: https://support.intego.com/entries/21639926-Personal-Antispam-Discontinued
Once Personal Antispam has been removed, you can just remove the folder manually (right click, remove).

HELP!! My Apple "MAIL" app. unexpectedly quits each time I open it.
My Apple "MAIL" app. unexpectedly quits each time I open it.
It will begin to load my mail, show the mailboxes and new e-mails and then all of a sudden quit.
I searched some of the Apple support and forums and have tried these things:
1. I trashed the "com.apple.mail.plist" preference file in the pref. folder.
2. I did an archieve install with Tiger OSX on my entire System Folder.
3. I erased my user>library>"mail folder"
4. I tried holding the shift key upon opening the program as suggested here but to no avail: http://discussions.apple.com/thread.jspa?threadID=479497&tstart=0
This has not resolved the problem. The program still quits every time I open it.
Pleeeeease help!!!!!!!!! DO YOU THINK I HAVE A VIRUS???

"You need to take this account online in order to download it."
If this is the result of having deleted the *.emlx files manually, you're probably seeing this error message because there is still a reference to them in Envelope Index.
Is there anyway to tell Mail to re-download these
mail files and reconnect them?
If they're still on the server, yes. Choose Get Info (⌘I) from the Action menu located below the mailboxes list in the main Mail window to open the Account Info window -- type "Account Info" in the search field of Mail Help for more information on this feature. Now, choose the account that has the problem from the Account popup menu at the top of the window. Does Mail display there the messages that are missing? What type of account is this (POP, IMAP, .Mac)? -
One of the email lists that I subscribe to frequently contains messages with images. It's a moderately high volume list with 20-30 messages per day. Inevitably, a few of those messages with attached images (according to the paperclip icon in the messages list) will arrive with no headers and no raw data. The display of the message in Apple Mail shows only the sender's name/address and the subject, nothing else such as the usual warning, "This message contains no content."
The people who run the mailing list don't think that the problem is on their end so I am here asking whether this is happening to anyone else and, if so, is there a way to correct it.Thanks to Linc Davis and dot.com for the replies.
Here is some add'l info that may or may not shed light on this issue.
I tried to follow Lin's suggestion to see if the message was intact in web view. Unfortunately, I was unable to find it. This is an Office 365 account. Apparently, messages are deleted as they are sent to my MaxOS X 10.10.1 account. I could only find two messages for today when Apple Maile shows more than a100 incoming. Thus, I was unable to cross check in this way.
However, I was able to replace this issue o/s of the mailing list server and Office 365. What I did was log into my iCloud web account and use Pages to send an email with an ePub attachment. I sent his twice, once to my @me.com address and one to my Office 365 account. The one sent to my iCloud account arrived intact. The one sent to my Office 365 account was empty – no attachment whatever. So this issue has to do with attachments as handled by Office 365.
Unlike the previous cases, I was able to see both the Headers and Raw versions of the email.
I see no clues in these data sets but include them here in case I have missed something. Here goes:

Apple Mail & .Mac Flaw - Eating HUGE Bandwidth
I received a call from the Comcast security service yesterday. Comcast told me that my cable modem reflected more than 1TB of data streaming thru it last month. Comcast threatened to turn my service off if I had another month like that.
I have 4 macs sitting behind a wired router with a secure firewall - the macs have IP addresses assigned by the router. File sharing is turned off. Norton anti-virus software running. I figured Comcast was wrong, until I checked the lights on the router. Data was just flying on and off my Mac Pro Tower (running 10.5.2).
I went into panic mode. I figured that somebody had gained access to the 500GB of data on my hard drive, which presented a very ugly ID theft scenario. so I wnet down the road of setting up a fraud alert, changed passwords (using a secure computer at my office, etc), canceling credit cards, etc.
I then added SurplusMeter, to see what was going on. Sure enough, huge amounts of data moving up and down. Surprisingly, more data was moving down than up. What the ****?
I then added Little Snitch. Firefox open, Safari open, Apple Mail open, and the data was flying. I didn't keep track, but I was downloading a GB of data as fast as my high speed cable modem would allow apparently, with lots of data moving up to.
The data stopped moving when I closed everything. That's odd. I opened up Firefox and Safari, and no data moved. I closed Firefox and Safari and then opened up Apple Mail, and the data started flying again. Little Snitch showed the connection to Apple Mail as the only existing network connection.
I use Apple Mail with a dotmac account. The only email program and provider I use. I had a ton of messages in my inbox on the dotmac side and the Apple Mail side, so I moved those to folders, archived or deleted them. The data was still flying. I deleted all plist and reindexed my messages on the Apple Mail side. No change.
I upgraded to 10.5.3 - no change.
I finally went back to the dotmac side, and found 37 messages in my SENT folder. The messages covered a year - they might have been messages that I sent using dotmac over the web while I was traveling. When I deleted those messages from my dotmac SENT folder, the data movement stopped completely.
This is a SERIOUS problem. I found two other mentions of this problem in this forum. No response to either message. Apple Mail - dotmac generated more than 1TB of data streaming over a one month period. I gather this is an isolated problem. But there is nothing special about my email usage or storage. (Apple Mail had been acting odd for a while - the program would hang 90% of the time when I would close it. I would have to use Force Quit.)I'm having the same problem, my inbox on my mail server is only 45MB, and I get about 100KB of email a day, but my mail app is somehow transferring 20TB a month to my mail server!!!! It all happens in the background so I don't even notice it going on.
I'm about to get kicked off my host. APPLE??? what the heck is going on? -
Apple Mail Infinite Incoming Messages
I have 9 email accounts setup in Apple Mail. They all worked on various Macs and iOS devices until the recent upgrades to iOS7 and Mavericks. On my Macs, all with Mavericks via a completely clean install, I am having the following issues:
* Mail using excessive (> 100% CPU on multi core machines) CPU as long as it is open
* "Mail Activity" shows an ever growning number of "Incoming Messages"
* Settings are not being remembered.
I have tried the following:
* Delete ~/Library/Containers/com.apple.mail
* Delete ~/Library/Mail
* Remove ALL accounts from Mail and "Internet Accounts"
* Rebooting
* Relaunching Mail
* Disabling accounts
* Pretty much every combination of the above
Nothing seems to work. The disappearing settings may be the result of trying many different combinations of the above methods and forgetting when I deleted them specifically but I am sure that they have disappeared at least once without that having been the case.CT - The problem is certainly not the standard behaviour so it is unsurprising that everyone cannot reproduce it. I did a new clean install after an upgrade some time ago and everything magically worked. I tried to list all the possibly relevant criteria in my original post but it is clearly not the whole story as I am no longer experiencing the problem
RedRacer123 - It is not a virus. It is just talk back and forth between your server and client (Mail). Especially with Gmail accounts there are a bunch of messages that are synced and archived behind the scenes which do not get displayed as new and unread (e.g. spam, chats). Regardless the problem I experienced and the problem that Megan62 is experiencing is different than just being unrelated: the count just rises and one can see that Mail is using a bunch of CPU doing something but it doesn't ever seem to finish whatever that is. I get a lot of mail but I do not have 250 MILLION messages when I see a counter go that high it is a bug in some while loop.
Megan62 - Sorry I don't have any advice other than try removing all your accounts email accounts from the computer and adding them back one by one. Hopefully whatever happened to cause the error will not happen again. I also think it might help to move as many emails out of your inbox as possible but I am not certain on that. -
I received an e-mail from the Mail delivery subsystem about undeliverable mail which was over 100 e-mails from me to all different unrecognized names and addresses, is this a Trojan horse and how do you get rid of it. I have Norton anti virus and it hasn't found anything.

Phantom Blank Spam blocking Mail from retrieving new mail in Apple Mail
Over the past few days my wife and I have both had difficulties downloading pop-3 mail from our accounts (from a UK based ISP, UKonline) onto our separate computers (Powerbook G4 and MacBook). I have no idea yet whether this is affecting other ISPs or other Mac or PC platforms or mail clients, but it is definitely affecting both of our Mail apps running under 10.4.7.
The problem seems to revolve around blank email messages being received into our respective accounts by at our ISPs mail server.
These blank messages, presumably some form of spam have no sender, no recipient, no date, no source code, no body text and no subject.
These 'phantom' blank emails appear to be the root of the problem as once they are manually removed from our server-side inbox (either through Apple Mail's 'Get Info' / 'Remove from Server' function, or via our ISPs webmail facility), the email starts picking up mail automatically again–immediately, without any other intervention other than clicking 'Get Mail'. Until they are removed, Apple Mail will NOT collect any more mail, automatically or manually through 'Get Mail'.
I have contacted my ISP and to date had no firm response from them. One of their operatives suggest I contact Apple as his Windows PC email still works and retrieves mail when these blank phantom messages reach his server-side inbox waiting to be collected.
The fact that these messages have no date means that under Mail's 'Get Info' / 'Remove from Server' facility, they always appear at the top with the CURRENT date and time when sorted by date. In this way, they are easy to spot. Also, if sorted by size, they also appear at the top because they are 0k in size. They appear to act as a blockage to receiving new mail until they are cleared.
I'd be grateful to hear if anyone else is having this problem or has found a solution to it, or indeed whether this is an ISP problem.
With thanks

These 'phantom' blank emails appear to be the root of the problem
as once they are manually removed from our server-side inbox
(either through Apple Mail's 'Get Info' / 'Remove from Server' function,
or via our ISPs webmail facility), the email starts picking up mail
automatically again–immediately, without any other intervention
other than clicking 'Get Mail'. Until they are removed, Apple Mail
will NOT collect any more mail, automatically or manually through
'Get Mail'.
What is your setting for removing messages from the server when downloaded by the Mail.app?
If set to right away, does this have any effect?
One of their operatives suggest I contact Apple as his Windows
PC email still works and retrieves mail when these blank
phantom messages reach his server-side inbox waiting to be collected.
Of course - especially if this operative is using Microsoft's Outlook or OE which usually don't have problems downloading anything including viruses, adware and spyware.
I'm not sure why these "Ghost" spam messages cause this problem with the Mail.app but these are obviously sent by a spammer to cause problems.
How about your ISP doing something about blocking all messages at the incoming mail server that are completely blank such as these so they don't arrive in any of their customer's Inbox mailbox at the server since these messages are intended to cause problems and are completely blank anyway? No different from any other type of spam or as messages are scanned for viruses at the server. Although Apple needs to look into this, your ISP is not completely off the hook or has no responsibility IMO. -
Has anyone started to experience crashes in Apple Mail?
I have happily been using InDeve Mail Tags for a few years
The application was updated, I installed and since then Mail crashes seemingly randomly while composing messages or replies
InDev support has been following with me.
The tech guy had me send some logs and noted that the crashes seem involved with JavaScript (not Java)
OF course I have no clue what might use JavaScript.
Wondering if my issue is idiocyncratic or if MAIL perhaps has changed and thus there is now conflicts with some software?
I am trying to check if I have any third party software needing updating which mIght impinge on MAIL.
Suggestions welcome1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, and a technological fix is not going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the scam artists. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
Software of any kind is distributed via BitTorrent. or Usenet, or on a website that also distributes pirated music or movies.
Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, your browser, or anything else.
Rogue websites such as Softonic and CNET Download distribute free applications that have been packaged in a superfluous "installer."
The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
High-priced commercial software such as Photoshop is "cracked" or "free."
An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission.
Conditional or unsolicited offers from strangers
A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
You win a prize in a contest you never entered.
Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
Anything online that you would expect to pay for is "free."
Unexpected events
You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an institutional policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices. -
This started today. I cannot send e-mail from my Apple Mail app to anyone with an AOL e-mail address. I get the following:
SMTP error from remote mailer after end of data:
host mailin-03.mx.aol.com [64.12.138.120]: 554-:
(ISP:B2) http://postmaster.info.aol.com/errors/554ispb2.html
554 TRANSACTION FAILED
I use earthlink.This has nothing to do with the Mail.app.
Per the link included with the return error message.
Error 554 ISP:B2
554 ISP:B2
http://postmaster.info.aol.com/errors/554ispb2.html
EXPLANATION:
The IP address on your ISP's network has generated a high volume of mail to AOL and has exceeded our rate limit. Possible causes include a compromised or virus-infected personal computer or a non-disclosed server relaying mail within the ISP’s network.
SOLUTION:
Please contact your ISP for assistance in securing your computer or have them Contact AOL to alert us to the addition of this mail relay.
If you need additional information please Contact Us.
Since it is doubtful your Mac is either compromised or virus infected, I suggest you contact Earthlink first assuming Earthlink is your ISP used for connecting to the internet. -
Apple mail - Ethernet - outgoing mail
I'm having issues with sending mail from my Apple Mail (Version 3.5).
Never had issues before, but flatmate just got rubbish Tiscali broadband equally rubbish (and mac unfriendly) router. Can't connect wireless-ly so am using an Ethernet cable. Internet works fine, as does receiving mail - just sending that is a problem.
I have tried changing the SMTP ports, tried using the tiscali account settings to set up another smtp server, but neither, nor in combination works.
can anyone help?Hi there,
My guess would be that port 25 is blocked by your ISP... A good many of them do this on non-commercial accounts as an anti-spam/anti-virus measure.
I would suggest that you need to switch your sending mail server to smtp.tiscali.co.uk as this is probably configured to allow smtp connections that originate from one of their IP addresses.
One other thing to check is that SSL is not turned on for smtp... Choose edit server list from the popup and then click advanced... make sure that the port is 25, SSL is off and that no authentication is required.
Hope this helps - Anton

Can't send in Apple Mail with .Mac - authentication problem
I use Entourage on my laptop for my business account and Apple Mail on my laptop for my .mac account. Sometimes when I travel and am using hotel and Tmobile wireless hotspots, I have to turn off password authentication for my SMTP server in order to send mail. This works like a champ in Entourage, but when I try to turn off password authentication in Mail for my .Mac account, it automatically still tries to authenticate! This results in me not being able to send .Mac mail. I tested this in Entorage on my .Mac account, turned off authentication for smtp.mac.com and it works, so this is definitely an Apple Mail problem specific to .Mac. Has anyone else experienced this? Is there a fix? I have tried to create a new smtp.mac.com account in Apple mail that does not authenticate, but somehow it changes into an smtp account with password authentication. Help.
I've been sending ".doc" files from both Mail and Entourage for some time without a problem.
Having said that, is there a chance that your Internet Service Provider is somehow blocking some file types?
I've recently come across a cpouple of European internet providers who do block executables and key file types that are known to cause problems or that might contain viruses/trojans. -
What about html email on Apple Mail 1.3.11 (v622/624)
Does anyone know of a good tutorial about html email? I understand about the
coding of the email proper, but my question is how you get the html to "link"
as email content, how one posts to his server, etc. I've seen a lot of tutorials
that explain what works with what email servers but have yet to see how you do these basic things. Finally, does the Apple Mail version I'm using below
accomodate html email? I've already coded a simple email in html but have no idea now what to do with it...?
using Mail 1.3.11 (v622/624)with OS 10.3.9
thx people...bqAnother issue with Mail (v3.6, 936); As I was responding to an e-mail this morning my cursor suddenly went nuts! It was as if the "return" key was being held down and it just keeps going! I can hold down the delete key to counteract it but as soon as I let up it starts right back again! Crazy! Might this be a virus of some sort? Anyone have any ideas?

Why does my Apple Mail insert old messages into the body of new emails?
Why does my Apple Mail insert old messages into the body of new emails? The correct sender's name will appear in the "From" column, but an old message from a different sender in the body. This happens randomly. I have an iMac OSX 10.6.8. I recently had the hard drive cleaned, but Apple Mail seemed to be running fine when I set it up again. Could this be a virus? What should I do about it? Thanks for any insights!
Thanks. While you were replying to my question, I went into notifications and figured
it out. Appreciate the quick response!
