Group Mailing List Emails Undelivered

My organization finally upgraded our servers. We jumped from Snow Leopard Server to Mavericks with the Server app. In the past we were always able to send emails to groups and for most part its working on the new server. However, we have an app (CCC) on the server that sends notifications to a specific group and the emails are bouncing as undelivered. The error message is "invalid characters in the message". Does anyone know a fix for this? The emails never bounced on the old setup and I can send them to any single user in the group on the new setup without a problem.

I have the same error, the log entry is (for this post i changed the domain to xxx.xx, other than that it is the original messes, up to an and including the typo in the error message, it really says "charracters" with two "r"s.):

Oct 11 09:32:14 xxx.xx postfix/local[4556]: 6B01FD32027: to=<partner@xxx.xx>, relay=local, delay=0.04, delays=0/0/0/0.04, dsn=5.3.0, status=bounced (Command died with status 1: "/Applications/Server.app/Contents/ServerRoot/usr/libexec/MailService/list_serv er_post post partner". Command output: /Applications/Server.app/Contents/ServerRoot/usr/libexec/MailService/list_serve r_post invalid charracters in message )

Additional information:

The text in the message is not important, I don't get any message delivered, even an empty one.
OS X version is: 10.9.5
Server version in: 3.2.1
Before the update the list worked and I had OS X 10.9.4 and Server 3.1.2

I hope this information helps to find the bug.

Best regards,

Markus

Same here, too. I wonder about the misspelling in the error message: charracters

I've isolated the problem on my site to sending group emails from Thunderbird, when there are accented characters (say a single é) in the message body.

This can be a plain text or html (multipart) - as long as the Content-Transfer-Encoding header says "8bit", the list server will bail. Any other individuals in the "To:" field receive the message normally, but the local group email addresses make list_server_post fail and return "invalid charracters in message".

Outlook and Apple Mail seem unaffected, possibly because Outlook doesn't set a transfer encoding and Apple Mail uses "quoted-printable".

I'm experiencing the same issue and the summary of the problem by glen.circle above seems a very accurate description of what I am seeing.

We are still running OSX 10.9.5 + Server 3.2.2 and what I would like to know is if upgrading to OSX 10.10 or 10.11 has solved this problem for any users who experienced this problem while running 10.9.

Any shared experiences about whether upgrading solved this problem or not, or any other solutions to this problem would be greatly appreciated.

Thanks.

We were experiencing the same problem here (Server 5, El Capitan), only with emails sent using Thunderbird.

We fixed it specifying the correct Encoding (Unicode) in Preferences > View > Format > Advanced

Since then, all emails are now properly sent to Groups.
