Mail service rejecting all external mail

I am running Snow Leopard Server 10.6.2 and when I began setting up the mail services I was able to get internal mail working just fine, however, any messages sent from external sources are rejected. The sender receives a permanent delivery failure message: The error that the other server returned was: 550 550 5.1.1 <emailaddress>: Recipient address rejected: undeliverable address: User unknown (state 14). I should note that I am using DynDNS's Mailhop Relay service, but that appears to be working normally as I can see the connections from the mailhop servers in my SMTP log.
I have tried disabling greylisting as posted in other threads to no effect. I have disabled filtering of any kind, still to no effect. At this point, I'm not sure what else to try, as at this point I'm in a little over my head.
Any assistance would be most appreciated, thanks.

I finally figured it out. My SMTP security settings were being mis-reported by Server Admin. The server was requiring authentication from approved mail servers when it wasn't supposed to.

Creation of transport rule to send all external mails through a particular server for a specific user..

HI,
In our Organisation We have a question, is there any possibility to create a transport rule for sending all external mails through a particular server by a specific user.
in our organisation we have exchange 2007 one mailbox server and two hub transport servers...and we are using symantic gate way..

Hi,
Based on my knowledge, we can use the following transport rule to make that except with one user, other users cannot send outbound external emails:
And I’m afraid that there is no Exchange feature to make one specific HUB server rout all external emails.
Because if a Send connector is configured to send messages to an external domain, any Hub Transport server in the organization will route a message for that domain to a source server for that connector to be relayed to the destination domain.
If you have any question, please feel free to let me know.
Thanks,

Configure sendmail to reject all incomming mail?

how would i configure sendmail on solaris8 to reject or trash all incomming email and still maintain capability to send email?

I found this thread useful and wonder why it some of this information isn't more readily available. Webservers shouldn't be running at mailservers and so the sendmail daemon doesn't boot up. Mail at cron and through .cgi/perl scripts utilize the sendmail on the servers I manage.
BUT -- in the last six months I find I'm having to reconfigure the sendmail.cf to find a way around an email configuration problem in our networks somewhere.
I've normally used the smart relay without problem. Now, even though I have the "connect" for mail going out to several different mail relays on the domain, the mail does not get delivered. I've tried to trace it down to one relay and have been unsuccessful.
The solution, and I don't understand it, is that we've setup a mail relay on a windows box in our domain and I've edited the sendmail.cf to use that mail relay instead of the smart relay.
In addition, and this is really strange to me, but I'm not a sendmail guru -- we're masquerading as a hotmail.com
If we don't masquerade as hotmail.com and use our own relay, the mail receipients don't receive mail occasionally. Both of these have to be in place for it to work successfully.
I think someone, somewhere, has a rule setup incorrectly, but it's beyond the relays we normally default to. With the mail relay setup in our domain, it accepts the mail because it's a relay, but what kind of rule would they possibly setup that accepts us masquerading as someone else???
Can anyone help explain this?
I personally would love to see some documentation on how an SA could setup sendmail.cf for their webservers as outgoing and have it RIGHT.
Thanks for listening.... feel free to say something. :-)

I recently changed my e-mail hosting service, and all my mail in my iPhone just disappered, How can I get it back? How can I prevent from it happening again?

As soon as I changed de Pop settings in t, all my mail disappered in a matter of minutes, Why? How can I get it back? I did full backup a couple of weeks ago, can I recover it from there?

Hey jartansmom,
Thanks for the question. You may need to configure the outgoing mail server for the account. The following resource will outline how to navigate to these settings, however instead of adding a server, you’ll then want to update the settings with your correct username and password:
iOS: Configuring additional outgoing mail servers
http://support.apple.com/kb/HT4519
1. Tap Settings > Mail, Contacts, Calendars.
2. Tap the Mail account for which you would like to change the settings. If you configured your account using any of the built-in presets, IMAP, or Exchange, you may need to tap Account Info on the following screen.
3. On the Account Info screen, locate the Outgoing Mail Server section and tap the existing SMTP entry. A list of SMTP servers will appear with the Primary Server and Other SMTP Servers.
If you need help with your mail settings, you can utilize this tool:

Mail Services and Backup MX/mail services

I have a question regarding backup mail services and acceptance of incoming messages.
As of last week, I am new to the world of Mail Services in OS X Server 10.4. Last week, our current email server died and I was forced to take an Xserve G4 that had OS X Server 10.4.10 (unlimited) and setup mail services in order to receive and send mail. I went to a website called osx.topicdesk.com and followed their instructions for front-line spam defense and clamAV updating (and switching to clamd) which all appears to be working OK.
Because our old email server was having some hardware issues for the past several months that I had been working on, I had the feeling that failure might happen. So what I did a few months ago was sign up for Google Apps and their mail service. I added their MX records under my primary mail server so that in the case of a failure of my server, all mail would be passed to Gmail and everyone could get to their mail immediately (as any prolonged downtime won't work since this is a daily newspaper). This did work, for when my old server died, all the mail went immediately to the appropriate Google Apps mail accounts. After about a day of setup on the Xserve, I got the mail services running OK. I gave it all the same IP info as the previous server so that the mail would just start working without having to edit DNS records and such.
The problem I am having seems to be this: While I get most mail, some of my mail is still getting sent to the Google Apps accounts. For example, I have one user, Jane Doe, at [email protected] who gets most of their mail from connecting to the OS X Server, but about 2 - 3 emails a day get passed over to the Google Apps server. I have run DNSStuff.com tests on the mail connections, and I always get a good fast response out of the OS X server. My thinking was that mail would only be passed over to backup mail servers if the first server listed in the MX records was unavailable or offline. In all of my testing, my server has responded every time. The server is connecting via a gigabit network connection (good response), is a dual G4 1.33Ghz, 60GB hard drive with 2GB of RAM. This server doesn't do anything else except run Mail services (and web services for squirrelmail), it doesn't even have file sharing turned on.
My old email server was a Pentium II 400mhz with 348MB of RAM, and it caught all mail, so I know that the Xserve should be able to handle the load without being busy. Is there any reason that my Xserve would be rejecting mail and they would be siphoned off to the Google accounts?
Is this even a possible scenario to fix the problem: Setup a backup MX "queue" account somewhere with one of the BackupMX online services that will catch these stray emails and then send it back to the primary server? But then can be turned off quickly to allow mail to go to the Google Apps accounts if my server went down. In other words, the DNS record would show my primary as 1, the backup mx service as 2, the google servers as 3, 4, 5 and so on. Can Backup MX services be turned off quickly like that so that if my server is down and I need email to be accessed immediately then just "turn off" the service (without modifying the DNS since that will take too long to propogate) so that mail bounces over to Google immediately?
I guess my first troubleshooting attempt should be to figure out why my OS X Server is not accepting all mail.
Thanks in advance for any help and suggestions.

When I first started with the company about 2 years ago, they had a really old Linux box (about 10 years old) that was used to host email. It was horrible. It would run OK, but if it ever went down or had a hiccup, it was an all-day project trying to deal with it. Unfortunately, the company did not want to spend any money on a new server or software of course. The answer I got was "well, it's just email". Sure, but if email EVER goes down for more than 15 seconds, all of the employees go into seizures and scream that the place will have to shut down. I work for a daily newspaper, so everything is running 24/7.
Knowing that one day that box was going to just die, I looked into some backup MX services. As pterobyte had mentioned is that with a secondary MX, the problem is that no one can get their mail at all until the primary server comes back up. I knew if that server ever went down, I had nothing to take its place, so I would have to order something or get a server from another location to use. Being unfamiliar with OS X Mail Services, I knew it would take me awhile to try to setup all the users and such. All the while at the newspaper, they would be screaming bloody murder that they needed email working for news, ads coming in, etc. And when I say if it goes down for 10 minutes they start getting into fetal positions in the floor screaming, I'm not far off exaggerating. I figured I was going to need something in place for them to check email while I worked on the primary.
Back in September/October 2007, I discovered that Google hosted free mail services call Google Apps. With Google, I could setup "matching" accounts and would still be able to use my domain name. You just had to use Google's servers as the higher numbered MX records. Luckily, I set up in time for back in November, the Linux box finally died. When it did, all email successfully went to their counterparts on the Google's servers. I had everyone go to the special Google Apps login site and they were able to check their email fine. I ended up having to take a box from another site and then I had another copy of OS X Server 10.4, so I loaded it and successfully setup email (with lots of help from pterobyte's tutorials). They were on Google's systems for about 2 days.
After the disaster, I went around and setup IMAP accounts on everyone's Thunderbird clients so that if our email server went down, they just simply check that mailbox. The nice thing with the Google IMAP is that they automatically see if emails are hitting that inbox from within their client. Right now, it still remains that the 2 original companies that hit the Google accounts still do. The city government email and email from a sister newspaper. Everything else gets directed to the primary server. Although sometimes that doesn't even work, as tonight I am having to work on a problem involving the Clamd app acting up - taking up nearly 100% of the CPU which in turn caused all the mail to be hung up in the queue. So since the mail server didn't "reject" the mail and grabbed it, their gmail "backup" didn't get anything in it. It was taking me forever to figure out what was going on, so I almost just told them to unplug the network cable from the email server so that everything definitely would be forwarded to gmail.
My wish is that I had a secondary mail server in house to not even worry about it - or better yet, I wished I could just outsource the email administration itself to someone else (like webmail.us which is now MailSafe). That way for the most part, they wouldn't lose email. But of course, the company doesn't want to spend the money or invest. Just gripe when the older equipment we have won't support what they want to do with it.
But the story above explains why I did what I did with the Google's servers. I do appreciate everyone's help and input on this particular problem. I am going to look around at the DNS and talk to at least our sister newspaper to see if I can see how they have their DNS setup.
Thanks!

Mail the spool to external mail ID

Hi All,
We have a requirement to setup a batch job for a Program/report daily and result/spool has to be sent as an attachment to external mail ID.
Please advise in steps how to configure the same
thanks in advance
Mahesh

Subject and Body can not be defined in SM36.
you should define the job like it would be printed.
To mail the output (List or Smartform) you have to code it yourself if you need to
define subject and body yourself.
It depends if you are doing an output using smartforms or with write statements/ALV
anyway for smartforms you become the spool-id in the "job_output_info-spoolids" return-parameter of the function. for list/ALV-Lists and write statements the actual spool-id is in SY-SPONO at runtime.
then you can use the function RSPO_SPOOLJOB_TO_OFFICE in the report to send the spool to the receivers you want. you can define subject and body also.
Regards,
Laurent.

Extracting e-mail addresses from all received mail

Hello,
We recently ran a competition on our web page and received approaching 5,000 submissions.
We need a way to collate a list of all the mail addresses of the people who replied.
The option in Window/Previous Recipients only applies to mail you have sent and not mail you have received.
Is there a way to export a list of received mail addresses?
Many thanks,
Ben

I wouldn't say there is no way...
Select all the messages;
Choose "Save As...";
Choose "Raw message source";
This saves a text file archiving all the selected messages. You can get the addresses from this file. One way is:
In Terminal, type
grep "^From " nameof_archived_messagesfile > ~/Desktop/listofsenders
(Ignore the colors in that text.) You can fill in the nameof_archived_messagesfile by dragging the file from the Finder and dropping it into the Terminal window. A text file named listofsenders should appear on your Desktop. It will contain a list of senders (along with some other junk). There are ways to refine this procedure, but I hope this will get you started.

Mail not downloading all e-mails from hotmail

Hi,
I have a MacBook pro 15inch running latest updates on OSx lion. I am having a real problem with mail application and my hotmail account. I have setup the hotmail account in mail and it downloads any new mails I receive but it does not sync any of the sent mails.
I also have an iPad which I use to send and receive emails and every time I reply someone using the iPad, there is no record of it on my mac if I replied to that person or not. Whereas if I reply to anyone using the mac, iPad shows all sent mails in sent folder.
Another problem I had (which is not currently main issue) is that occasionally it asked to put your password in for iCloud and hotmail account even if i check save to keychain.
Is there any way I can get my mac to sync all folders from my hotmail to mac? iPad does it with no problem..
Thanks in advance:)

I'm having the same issue and have tried deleting the account and adding again but I only have emails that came in yesterday after Mavericks installed. My thousands of emails from the server did not load. They are everywhere else but on the updated Mavericks computer.

Flakey internet causes Mail to forget all cached mail

Whenever I'm on a slow/flakey link, Mail decides that all of my cached mail is invalid, and then wants to download it all (~10,000 emails) again. This is very annoying, since it does it at least once a week whenever I'm traveling.
It's driven my sister to abandon using Mail at all.
And, annoying, but wouldn't be a problem except that Mail keeps redownloading my emails, the "take all accounts offline" button is a toggle, so you can't just frob it and have Mail stop trying to talk to all of the servers.

I waited until Mail dropped my emails again, tried the suggestion.
Whacking com.apple.mail.plist did cause Mail to forget all of my accounts, but thankfully not my rules and signatures.
However, it didn't keep mail from dropping half my cached mail a week later.
Luckily my current link isn't quite as flakey as it could be, despite being in Iraq for the next several months.

Can the iPhone only pull inbox mail and not all unread mail?

Yahoo correctly filters my mail into inbox and spam. The iPhone pulls ALL unread mail rather than just that from the inbox. Anyway to fix this?

What is unread except for what is in your Inbox mailbox?
Are you accessing a free Yahoo account with the iPhone's Mail client, and did you use the Yahoo account preset when creating your Yahoo account?
If so, the Yahoo account preset on an iPhone creates the account as an IMAP account with the iPhone's Mail client. With an IMAP account, the email client used to access the account keeps all server stored mailboxes for the account synchronized with the server. All messages received by the account, and available in the account's Inbox mailbox on the server, will be available in the account's Inbox mailbox with the iPhone's Mail client - which keeps the mailbox synchronized with the server. If spam is received at the server and is available in the account's Inbox mailbox at the server, the same messages will be available in the account's Inbox mailbox with the iPhone's Mail client. This is how an IMAP account works.
With a POP account, any messages that remain in the account's Inbox mailbox at the server will be downloaded when accessing the account with a new email client, and will be shown as unread when downloaded by a new email client used to access the account. This is also normal for a POP account when accessing the account with a new email client.
The iPhone's Mail client does not included a spam filter. Even if it did, new messages received at the server and available in the account's Inbox mailbox at the server will be downloaded - spam and all - which is the same for any email client.

Outlook and mail services/ can't send mail to external emails

I have been setting up os x server as a mail server for my company. I bound open directory to active directory but could not manage mail for the active directory users that way, so I started creating new users through open directory.
I've hit a couple snags that I can't quite figure out. First, I can send and receive mail to other open directory accounts fine, but not externally. I've set up my MX records and a name records for my Internet domain.
I can receive emails from an external email address, I.e. Gmail, but cannot send to them. It gets stuck in the mail server's queue. Information logs says operation timed out for smtp.gmail.com and their ip address.
I forwarded the ports, 25, 993, etc from my dsl router to my firewall router, then from there to my mail servers static ip address. I'm at a loss. If it matters, I'm on a residential dsl currently, my ISP claims to block port 25, but in the log it looks like it goes through and sees gmails ip.
Secondly, this is all through the mail.app for my MBP. When I set up outlook 2003 on xp, I can send emails, but it doesn't download any. No errors in either the information log or outlook, outlook says it completed successfully. If it matters, I was getting an error from outlook previously, helo error for not a fqdn, but I deleted a line in the main.cf that required fqdns.
I appreciate any help.

***EDIT*** I have outlook working....now it is just the external email thing. Again...my ISP says they block port 25, but I went into /etc/postmail/master.cf and added to have SMTP go on port 2525 and still no go. Any help would be greatly appreciated!
***END EDIT***
I apologize...here is the SMTP information level log for sending to gmail

Error while sending mail from SAP to external mail id

Hello Experts,
I am blocked by the below problem.
I am trying to send email from SAP to an external email ID. I have tried using Class approach as well as the function 'SO_DOCUMENT_SEND_API1' for the same.
Everytime i get the following message:
Internal error: CL_SMTP_RESPONSE ESMTP error code is not known. 554 554 <email address> Sender address rejected.
I am not at all able to figure out why this type of error is coming.
The same code is working on the development environment but not on the test system.
Please reply back asap as i am completely blocked due to this.
Thanks/Regards,
Himanshu

Hello Priyanka,
Actually, I performed the following two steps in order to solve the issue:
- In transaction SICF, the node for SAPConnect must be active. In our system, this node was in inactive state. Hence I activated it.
- Then In transaction SCOT-> Settings menu--> default domain should be 'xyz.com' if the email addresses in your company are maintained with a suffix xyz.com.
But for me the problem didnt get solved here..
The problem that i am facing now is that if in my user profile, I have the email address maintained, then i get an error saying 'Sender address rejected'. However, if i goto transaction SU01 and clear the email id, the mail is successfully sent to outer world.
You can try the above mentioned two steps using SICF and SCOT. If the problem does not get solved then try clearing the mail id in ur user profile.
Hope this helps. If you find an answer to the problem of the mail id getting cleared, then please let me know..
Regards,
Himanshu

In Mac Mail 7.1 How do you stop incoming mail from showing all related mail. The link at the top doesn't do the trick.

When I receive an email every single mail that has the same subject shows up in the inbox as a separate email. It is very confusing when you see a bunch of emails and have to try to figure out the actual order. The point is that I simply do not want to see all the other emails in the same window. All I want to do is read the current email. And if that particular email has any previous emails in the email thats OK but what is happening is you see the related email twice. This was not occurring in the previous version. The botton on the top that says Hide Related Emails does not work continuously. I am using Maverick.

From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Test.

Can't cut and paste in a web based e-mail service. (Not G-mail)

I belong to a membership site that is coaching me on e-mail marketing. I want to cut and paste different bits of information and ad links etc. to emails that I am sending out through the site.
For some reason, Firefox will not allow me to cut and paste when I am in this particular site??
I can cut and paste in Microsoft Word and other programs with no problem. But when I'm on this particular site it's no deal.
This is very frustrating. What can I do to resolve the problem.

I've had this happen a couple of times. Seems it just gets a bit borked sometimes.
Best thing to do is close Pages (or whatever), then do an iOS reset (hold power button then home button till screen goes blank and apple logo comes up and then let go).
Cut copy paste should work again as normal.
