[Mailman-Users] many "Subscription disabled" messages after movinglist to new server

[Andrew Watson]

The bounce notices I get look legitimate. They typically include something like:

Reason: Remote SMTP server has rejected address
 Diagnostic code: smtp;550 <albert at cvc.uab.es>... User unknown

Mailman's smtp-failure log contains many instances of lines like this (edited, vsadmin at mysite.com is the list administrator)

Jan 12 20:48:44 2010 (70977) Low level smtp error: Connection unexpectedly closed, msgid: <mailman.1063.1263328366.70976.visionlist at mysite.com >
Jan 12 20:48:45 2010 (70977) delivery to vsadmin at mysite.com failed with code -1: Connection unexpectedly closed

There are also a few like this:

Jan 12 20:02:54 2010 (70977) Low level smtp error: (48, 'Address already in use'), msgid: <mailman.561.1263325634.70976.visionlist at mysite.com >
Jan 12 20:02:54 2010 (70977) delivery to visionlist-owner at mysite.com failed with code -1: (48, 'Address already in use')


These log messages commenced on Jan 12 (today).
