[Mailman-Users] Low level smtp error: Server not connected

[Leonard Jacobs]

I am trying to run Mailman 2.1.9 on a CentOS 4 server with postfix 2.4.1.  I had Mailman 2.1.5 running on a slower system and wanted to offload some apps to this newer server but am having problems. check_perms has no errors. Creating lists works fine and when postings are submitted the messages are delivered to the list admins re posting verifications.

But only a few of the messages are getting delivered. logs/smtp-failure shows many of this type of error:
"delivery to someone at gmail.com failed with code -1: (104, 'Connection reset by peer')" I am also seeing many " Low level smtp error: Server not connected, msgid" errors. I did try all the suggested fixes in the FAQ including adding the line to get error output in the logs/error file. And this file is showing successful delivery, such as 
"May 26 16:33:44 2007 qrunner(20744): reply:   '250 2.1.5 Ok\r\n'
May 26 16:33:44 2007 qrunner(20744): reply: retcode (250); Msg: 2.1.5 Ok
May 26 16:33:44 2007 qrunner(20744): send:   'rcpt TO:<somebody at surewest.net>\r\n"" 
but the majority of the messages are simply stuck in the qfiles/out and qfile/rety directory.

I am running python 2.5.1 so that I could get the error logging to work but this problem happened with python 2.3.

Any suggestions would be greatly appreciated since my mailing list no longer works at all.

Thanks.
