Subject: ImportError: No module named header (after upgrade to Squeeze)

Date: Sun, 06 Mar 2011 14:02:41 -0500

Package: mailman
Version: 1:2.1.13-5
Severity: normal


After upgrading from Lenny to Squeeze mailman stoped delivering mail. The
incoming messages would end up in the list archive. But the message pickle
ended up in /var/lib/mailman/qfiles/bad. The following log entry was noted:

Mar 06 13:03:09 2011 (2703) Uncaught runner exception: No module named header
Mar 06 13:03:09 2011 (2703) Traceback (most recent call last):
  File "/usr/lib/mailman/Mailman/Queue/Runner.py", line 100, in _oneloop
    msg, msgdata = self._switchboard.dequeue(filebase)
  File "/usr/lib/mailman/Mailman/Queue/Switchboard.py", line 160, in dequeue
    msg = cPickle.load(fp)
ImportError: No module named header

Mar 06 13:03:09 2011 (2703) Skipping and preserving unparseable message: 1299434588.9720759+4fc58e0100834649217e9bd5cdd1976fe84f5c48

Installing python-mailer and restarting the qrunner solved the problem
for me.

Copying the message pickles to /var/lib/mailman/qfiles/virgin reinjected the
stalled messages.
