Is my mac mail sending spam?

I have 4 different emails for various business that I own.
Today I got an email from one of my own accounts to that same account. It's about some kind of Canadian online pharmacy.
I know I did not send it.
What should I do about this?
For a few weeks I've been getting emails bounced back to me saying undeliverable to a certain address. I'll look at the email and it's not one I've sent or know anything about? I just delete and move on. However I'm getting about 20 of these spam emails a day. Very frustrating.
What can I do?

Many spammers obtain email addresses that are legitimate and use them as the From or Reply To addresses on the spam they send out. This is to prevent normal junk mail filters from sending their spam to the junk mail or trash folder.
Not much you can do about it besides changing your email address then installing software for anonymous browsing and email. This may not be a good solution for business usage unless all your recipients know who you are because such software hides where the email is from.

My mac mail sends a false return address

my mac mail sends a false return address.
isp (Att yahoo) indicates false return address is one of thiers, but cannot understand how our computer finds it inorder to send out. The false address lists an odd email server (pimout) instead of sbcglobal ([email protected]).
isp suggests mac mail must be making contact with the server, and finding this address, some how in a search for it's appropriate address is the theory, because it is one of their's.....but has never been our address..
So, I don't really care why, but figure if I trash the right lib/pref file, I can lose this problem.

Paul, this is not a very clear description of your problem, but let's give it a try;
In your Preferences for Mail, Accounts, what do you have there as email name? the correct address?
Can you send me an email (provided somewhere in my profile when you click on my name) so I can see what the data in there looks like?

How do I change the hostname used when Mac Mail sends EHLO

Hi All,
I work for a tech support group and one of our clients is experiencing some trouble sending emails. When they connect to their outbound mail server Mac Mail sends the EHLO command with a hostname like 01:23:45:67:89:ab.home
Another Mac on the network sends a hostname like 00:A0:C9:14:C8:29.home2
So they appear to be the a Mac address for the computers NIC followed by a generic location in this case .home, not sure if thats a generic Mac thing or something they chose to configure but because the hostname is not an ip address and contains ".(dot)home" the outbound mail server our client uses believes it to be a domain so then rejects it as an invalid domain when a lookup on it fails.
I've changed the hostname of one of the Macs using the command "cutil –-set HostName new_hostname"
This has changed the hostname when checking it by the hostname command in a Terminal but Mac Mail still persists in using the old hostname. We've tried rebooting the machine and rebooting the machine with the left shift key held down as I believe this does some kind of rebuild of configuration files, but still the old hostname is send when Mac Mail sends EHLO.
How can I force Mac Mail to pick up the new hostname or is there something else I need to do to change it?
thanks for any assistance you can provide,
Martin

Help! My home mac is sending spam emails!

Hello,
I am a long time mac user, and have never encountered this problem before. In fact I've only heard about this on windows:
My home mac is sending out spam via my primary email address.
I discovered on Friday morning that sometime on Thursday afternoon a bunch of spam emails were sent out to people present in my addressbook while I was on my home Mac (there are other unfamiliar address too, but many from my addressbook). I checked my home directory for viruses using Norton Antivirus and found a virus: Trojan.ByteVerify and some related files. I deleted them, and rechecked the directory, and found nothing more, so I thought that was the end of it.
However I checked this afternoon and found two more batches of spam emails had been sent, yesterday early afternoon and again today late afternoon. Norton continues to find nothing in my home directory, nor does Little Snitch report any unsolicited activity.
I assume my Mac is to blame, as the emails have only gone out when I am active on the computer and connected to the internet.
I have the firewall on, and Norton checks all downloads, but beyond that I'm not sure what else I can do. I am right now working from an 'emergency' drive which I hope has not been affected.
I am prepared to erase my primary startup drive and rebuild it, IF that will solve the problem, but I am looking for some guidance. None of my tools seems to be reporting anything wrong, and yet something definitely is! I thought Mac OS X was immune to this sort of thing, but it appears not.
Any help would be appreciated as to what I can look for or do (aside from giving up and rebuilding the startup drive).
Thank you,
Rob

Hi folks,
An update 10 days after the problem first appeared...
It seems clear that:
- someone is able to mimic my old email address and send spam to people, making it look like it is coming from my address. At least some of these spam emails are showing up in my "Sent" messages folder in the compromised email account.
- Somehow, the spammer has obtained my address book, which is being used (in part) as a source of addresses for spam recipients. I know this because among some unknown spam destinations are scattered addresses I have in my address book from both work and personal life. I have no idea how this could have happened. I have not emailed my address book anywhere. I have in the last month or so used dropbox to start synchronizing address book between home and work macs (so the master resides on dropbox), Those are the only places my address book resides. I see no sign that my dropbox account is compromised, but I might abandon cloud computing for now after this!
- Spam (pretending to be me as a source) is only being sent out when I am actually using my home macintosh computer. I am certain of this now, after 10 days of viewing the pattern. The first spam was Thursday June 24, when I was on the Mac, and there have since been about 6 or so spam 'waves'. None on the 25th, but on the 26th, 27th, 29th, and 30th. I did not turn on my home Mac on the 25th, 28th, nor between July 1-5, and there has been no spam on those days. Is it possible for someone to monitor my IP address and send spam out when the monitor sees me communicating with the outside world?
What I've done:
- I created a new mac OS system from scratch on my home computer, containing no files with modified date June 24 or later. That new system is using Norton Antivirus for Mac, firewall on in stealth mode (allowing only email, web, and normal system operation), Little Snitch (I've enabled very few operations to be allowed automatically), and using a Mac OS X account that does not have administrative access.
- I have tried to change the settings of the AOL free account (at least change the password), but am unable to do so. When I log into my account on the web, click settings and change password, it asks me my security question, then I get a French page (not my choice) showing some of my account settings, with nothing to click that would allow me to change settings. There also seems to be no way to delete or cancel an aol free email address account; the best advice I've seen is that it will be deactivated after 90 days of inactivity, which in this case won't happen if spam is being sent from that address and appearing in the Sent folder. I will continue to investigate ways to do this; I might end up having to write a snail mail letter to AOL Canada asking them to delete the compromised account.
- I have pretty well abandoned the compromised email account, migrating most of my email subscriptions to a new email address and informing who I can that the old email is a spam source. Is there any way to report the email address as spam centrally?
- Finally, I am going to contact my ISP today and see what they can do; maybe I can get a different IP address at home...
If anyone has further suggestions I would appreciate it. What a nightmare!
Thank you,
Rob

Mac Mail sending out multiple e-mails

Dear All,
My friend reports that today he is receiving 3 copies of every e-mail message that I send him. I'm working on a Mac Pro, Lion 10.7.5, using Mac Mail through Yahoo, and I have only one account. I have an iPod touch, but I have never sent e-mail through that device nor signed up for it on the iPod -- I only use my Mac desktop for sending and receiving e-mails. Anyone else having this recent problem? I never had it before today! Thanks.

Are you sure it's the Mac sending out the spam, or just spam masquerading as coming from your email account (the From: line is ridiculously simple to forge)?
While it's clearly possible to devise a system to cause a Mac to send out spam email (or any other computer for that matter), it wouldn't be terribly efficient for the spammer. Even when they take over zombie machines (and unpatched Windows XP systems are the favorites there) the spammer would prefer to use the machine to send out all kinds of email *AND* would attempt not to draw attention to the actual machine sending out the stuff.
That is, where it *appears* to be coming from will generally not be where it is coming from.
What malware prefers to do is "harvest" an address book from a user's computer (or, more often these days, from an online address book after phishing the credentials from the user) and then using that to send out emails to your contacts that look like they come from you so that they are more likely to be opened. If that's what has happened, there's nothing you could do to the Mac at this point to get that data back.
Again, while it is clearly possible to harvest that data under either OSX or Windows 7 from your address book in either platform, it is considerably more difficult to do that than to go after your credentials for an online site using a phishing attack and then make use of the contact information.

MAC Mail - Sends Mail but mail never arrives at destination

Hi,
I have Leopard installed and am using MAC Mail for email. I connect to Virgin email servers for mail. Mostly this works fine, however I have found that sometimes I send email to contacts and it never arrives and never bounces back. I think it only happens when I click 'Reply' on emails. The addresses are correct and I never get a bounce back. Anyone had this problem?

Hmm…I see two problems here: one is that your profile says you're running 10.4.10; if that's true, then you should update to 10.4.11 immediately, and you're in the wrong forum. If that's not the case, you need to update your profile so it accurately reflects the specific version of OS X you're running. And FYI: there is no MAC Mail; it's Mac. MAC is an acronym for something completely different.
As for your problem, as long as the mail is sent, what happens to it after that is out of your control. It's possible that Virgin is experiencing problems with their mail servers to that some of these emails are deleted before they ever reach their destination, and it's also possible that the recipients' ISP is experiencing that kind of problem, but it would be rare. It's more likely that something in the subject or the body of the email you're sending is being flagged as spam and that the recipient or their ISP puts them into a Spam type folder or just deletes them before they ever reach the recipient. Since I don't know what kind of emails you send or to whom, I can't be sure, but I'd ask my recipients about this first, then my ISP.

Whay won't my mac mail filter spam/junk?

It appears that, yet again,my email address has been sold on. I believe this time after I purchased a CD online. Ever since the transaction my mac mail has been flooded with unsolicited mail (loans/PPI/ credit cards/congratulations you've won... etc) and despite flagging and sending to junk spam mail (sometimes from the same server with the same content) still end up in my inbox. Why won't mac mail recognise this as spam/junk and what can I do?

Attaching jpg images in Mac Mail - sending to a PC

I've been looking for some current information on this problem. Most of the posts seem to be years old. Is there a working solution to attach images to an email and allow a PC user to download them like a regular attachment?

I am having the same problem with only a select few of clients. Sending pdf - fine, they arrive as attachments. Send a jpg and they are embedded within the email and they have to copy and paste the image out of their email into another program - thus risking the quality of their computers capacity to provide a good image. Then another client has no problem. Read everything, click on everything. I can buy a iconizer, but why do I need to buy a program to simple get the jpg to the client. And why do I need to read every post back to 2003 on why Outlook does this so I can use my simple - attach file within the mac mail. So now I have to go within my computer - control click and save the file into a zip - sometime adding another folder to group them all together. More clutter on my computer.
This is what is frustrating. Go on mac posts to find answers - they have you click on all these buttons and stuff. Go to pc outlook google searches and they have them clicking and doing all sorts of fixes. Can't these two computer software groups figure this out.
If it was happening on every client - then I would think it was me. If was happening on every outlook client - I mean everyone outlook receiver - then it is outlook, but it only happens with a few. What button within outlook does the client need to click on or off - it is that simple.
I might sound frustrated but I'm not. By the post out on the net that I read - this is happening a lot but no one specific answer seems to work. And it is all related to me with the client's outlook email service.

Mac mail send problem

hi
a problem with mac mail. while the laptop is at the office the mail program works fine, out of office it does not - it recives mail but does not send. we have our own mail server (leopard server) it's on the office network. We use IMAP. We connect via VPN to our office network so the SMTP is always the same. When the folder username-library-mail is deleted mail recreates it and sends mails for some time but then stops.
Thunderbird in the same macbook works fine using same SMTP port
what causes this phenomena?

Mac Mail sending messy code attachments to windows

I've sync 6 different mail accounts to my Mac Mail, but what it troubles me is that when I send Chinese emails with attchemnt (in Chinese too) the reciever Widonow users keep getting messy code with somthing like (鍛@?鍗＄墖.docx).
I've been look every where on Google can't find any good solution. I know that changing my Text Encoding works but I can't set it to defualt
I know there's an updates that windows can download so that they read mac's uni code, but I can't find the download link.
If I switch to Office Outlook would I still get this problem? or is there any better way that Apple can help me to solve this?

To thoughs just been searching, I just came across a app that actually solve this problem (well at least for Chinese attachment).
It's a new app develop by tencent called foxmail (http://foxmail.com.cn) it works fine for me.
you guys can go check it out. But this app's interface isn't as good as mac mail, but at least my colleagues stopped complaining at the mess code problem.

Mac mail sending issue

Hi,
I'm using Mac Mail to send my emails. I have them set up using IMAP with GoDaddy hosting my emails.
For some reason Mac Mail is not saving / recording all sent emails, especially emails sent with attachments. The recipient is receiving them all so they've definitely been sent, but they're not appearing in the sent items / sent folders.

Try rebuilding the mailbox. This can take awhile if you have a lot of mail.

Mac mail sending messages to people not on distribution

When sending a reply to a mac mail message that originally had several people in the distribution the reply message will send to everyone in the distribution even if you manually take out an address from the message you are sending out.

In have a similar problem. I consistently request that names of all people on send list to NOT be shown to individual addressees, but consistenly are sent all the names. Can this be corrected?

Mac Mail sends but does not receive

Hi
Big problem!
Just upgraded to Lion - and this problem was on Snow Leopard too - I tried to upgrade to sort this out!
Mail sends emails but does not recieve.
I own the server where it is trying to connect to - the emails are there - I can see them through webmail.
I have set up different email accounts on Mail and exactly the same for all domains and email accounts.
I have re-installed Mail - exactly the same happens.
I have used Thunderbird and it works!
So it has to be a Mail problem. Server is fine, OS is fine, other email is fine. Mail is the problem.
I think it has to do with keychain? Not sure though... I have tried literally hundreds of things but nothing works and I am at my wits end and run out of ideas!
Any suggestions would be warmly received!!
Thanks in advance
Rob

Hi,
I have the same problem with my incoming mail. I talked to the folks at Frontier (my ISP). They verified that a
test message I had sent was received. All account info appeared to be ok. I click on "get mail" and I do not
receive any new incoming messages. All connections succeed Using Connection Doctor, although the connection to smtp.frontiernet.net spins quite awhile before succeeding.
While I was composing this reply, I decided to try to send a test message to my wife's account. It came
through ok. I think I might have to contact Frontier again on this. When I set her account up they gave me a
different Incoming Mail Server name to use: pop3.frontier.com, whereas mine is: pop3.frontiernet.net. I believe
new accounts are being assigned to: pop3.frontier.com.
Also, when I'm showing all inboxes, Mine all have a symbol after them that looks like a lazy z. I am not familiar
with this symbol, but since I'm having trouble, I suspect it is telling me something. Help on this??

Mac Mail send and receive

Hi,
I have recently upgraded to Mountain Lion. My question is how does Mac Mail receive emails? I am connected to our Exchange 2007 server. I also have Outlook 2010 client running side-byside in Unity mode using Vmware. So now everytime I receive an email Outlook gets it first and about 2-5 minutes later Mail receives it. In order to receive it earlier I have to manually click on the Synchonise mail menu item.
Is there a way to manipulate the behaviour of Mail so it synchronises a bit sooner?
Many thanks,
vnayak.

Mac mail sending jpegs to a PC not sent as an attachment

When I send an email with images as jpegs they are not able to see them as an attachment. When they are revived on a pc in live mail they are stripped of the name and given a different name. My friends can not save them as a jpeg. If I send them in a folder they arrived in live mail as zipped.
My friends tell me that Mac is making the changes. When sending to another Mac everything is fine.
Does anyone have an explanation what is going on? I am on lion when I was on snow leopard there was no problem. All of this seems to be since I switched to lion.
Thank you

Do you tick the bottom box 'Send as Windows-Frienly Attachment' when choosing the attachment?
