Q: Mavericks mail server stops distributing group email after a few hours of usage

Same problem here and it's causing a big problem for my small business.  Anybody have a script that will stop and restart mail every so often?

I know this is not the fix you are looking for, but it's what I had to do, so I thought I'd share.

Hopefully, someone will be able to figure it out the "right" way!

I created this AppleScript that will stop and start the mail service every hour.

You can copy and paste it into AppleScript Editor, compile it and save it as an application.  You can then run it.  You need to run it from an administrator account and keep that user logged in.

If once an hour (every 3600 seconds) is too often, just change 3600 to however many seconds you want.

Be sure to change AdminPassword with the Admin user's actual password.

repeat

          do shell script "/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin stop mail" password "AdminPassword" with administrator privileges

  delay 60

          do shell script "/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin start mail" password "AdminPassword" with administrator privileges

          delay 3600

end repeat

Same issue here. Here is the entry in mail.log which never gets delivered.

postfix/smtp[11311]: CA7018A39B: to=<team@#####.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=5.2, delays=0.02/0.01/0/5.2, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as F105F8A3AC)

I'm experiencing the same thing here.  Have been manually restarting the mail server every few hours.

I have the same problem if anyone finds a perminat fix please post back.

We rolled back to 10.8

Same problem here. I can't get it to resolve. If this helps anyone find the solution I also noticed this in the List Server log files at the same time a user attempts to send mail to a group email address:

Given that you all are working with list groups, I thought I'd share that there is also a bug that prevents emails over a certain size from working, specifically with list groups.  This is different that the maximum message size that you can set.  This only applies to lists, and according to Enterprise Support, there is no current patch for it.  So, if you are not getting ALL your emails from the list server (when it's running), that might be why.  Here is the thread which talked about it and where I posted my horrible workaround: https://discussions.apple.com/message/23980388?ac_cid=tw123456#23980388 Since the fix replaces the functionality of list groups, it's also a work around for the problems in this thread.  Just keep in mind that it NOT elegant. 

What you are saying seems to be the same problem I'm experiencing, thread: https://discussions.apple.com/thread/5638034

Pinion Sofware:

I agree that it's the same issue.  So, I suggest you post to this thread https://discussions.apple.com/message/23980388#23980388  I am actively working with Enterprises Support, and they are in contact with a software engrineer.  They have already given me one thing to try (didn't work), but as soon as I get something helpful, I will post it.  If you have a small number of email groups, then the solution I posted will help you and prevent the list_server from locking up too (this thread).  It's not pretty, but it fixed all my mail group problems and everyone is finally happy in my office!

Got the same bug here, have follow this procedure to setup my mail group forwarding:

http://www.macjunky.nl/setup-email-forwarding-to-more-than-one-user-within-mount ain-lion-server/

works great but suddlenly mail fed to group stop to be deliver and I have to restart mail services to start receiving them again ????

If someone have any update on this one will be great.

Thanks !

Just wanted to pass on that I just got an email from Apple Support that they have setup a test environment and have been able to recreate the issue.  It is actively being diagnosed.  They are working on both the issue requiring a restart of the email service / list_server and the issue where large attachments sent to a list group are truncated.  I will keep everyone informed when I hear more.

When the server goes into this state, will messages be received and just not delivered?  If so, will stopping and starting the mail server clear out and deliver messages that are "stuck" in the queue?
