Hello list,
A week or so ago I ran across this problem on one of our mailing lists: A user had sent an email with an apparently bad subject line. This has caused mailman to stop delivering emails for that specific mailning list. Here's the error from the logfile:
Jan 05 21:25:10 2009 (23055) Uncaught runner exception: unknown encoding: Re: DDS 26073 : Imap - installation d Jan 05 21:25:10 2009 (23055) Traceback (most recent call last): File "/usr/lib/mailman/Mailman/Queue/Runner.py", line 111, in _oneloop self._onefile(msg, msgdata) File "/usr/lib/mailman/Mailman/Queue/Runner.py", line 167, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/lib/mailman/Mailman/Queue/IncomingRunner.py", line 130, in _dispose more = self._dopipeline(mlist, msg, msgdata, pipeline) File "/usr/lib/mailman/Mailman/Queue/IncomingRunner.py", line 153, in _dopipeline sys.modules[modname].process(mlist, msg, msgdata) File "/var/lib/mailman/Mailman/Handlers/ToDigest.py", line 91, in process send_digests(mlist, mboxfp) File "/var/lib/mailman/Mailman/Handlers/ToDigest.py", line 132, in send_digests send_i18n_digests(mlist, mboxfp) File "/var/lib/mailman/Mailman/Handlers/ToDigest.py", line 306, in send_i18n_digests msg = scrubber(mlist, msg) File "/var/lib/mailman/Mailman/Handlers/Scrubber.py", line 240, in process url = save_attachment(mlist, part, dir) File "/var/lib/mailman/Mailman/Handlers/Scrubber.py", line 373, in save_attachment fnext = os.path.splitext(msg.get_filename(''))[1] File "/usr/lib/python2.3/email/Message.py", line 731, in get_filename return unicode(newvalue[2], newvalue[0] or 'us-ascii') LookupError: unknown encoding: Re: DDS 26073 : Imap - installation d

The full subject line should be:
RE: DDS 26073 : Imap - installation d'application 'vacation'
so I think the apostrophe is causing havoc here...
I have searched mailing list and the search engines, and it looks like this error was a problem for people but has been solved in subsequent versions of mailman (we are running 2.1.5 on Debian Sarge). What I haven't been able to find out is how to purge out the offending email, and continue life as normal until we upgrade to Etch!
I should say that I have tried removing the offending file from $MAILMANDIR/qfiles/shunt and running "unshunt", but nothing changed.
Any suggestions are most appreciated. /Khosrow
