Hello,

I have an "interesting" on some mailinglist. All mails to this list get shunted with the error message: LookupError: unknown encoding: X-UNKNOWN This only happens when digestable is set to true. The funny thing about this, that I cannot figure out when this error occurs. It is only reproduceable on some lists.

• Not all lists with the digestable=1 have this phenomen, in fact only a few have it
• The problem is indepented from the mailer I use. Other lists work fine with all tested mailers
• The listowner told me that he didn't change the digestable option when mails stopped arriving at the list (he just changed the archive from public to private).
• The list worked fine for some month before it "stopped working" at the beginning of april
• Updating mailman to 2.1.4 and several restarts didn't help
• There were no lockfiles that could have caused this problem
• Skimming the code in Scrubber.py und Message.py didn't help me.
• My current "hotfix" is to disable the digest option on the affected lists. But this cannot be the solution forever....

My setup is a gentoo-linux box with mailman-2.1.4 and python-2.3.3 I have absolutely no clue how this problem was introduced to my system an why it is just limited to some list.

There is a (quite old) bugreport about this problem from another guy: http://sourceforge.net/tracker/index.php?func=detail&aid=803729&group_id=103&atid=100103 but there's now hint there were the problem lies.

I hope you give a hint were to look for the source of this problem. Mainly I just want to understand what's going on here.

Here's the excerpt from my error log: Apr 26 18:27:05 2004 (17449) Uncaught runner exception: unknown encoding: X-UNKNOWN Apr 26 18:27:05 2004 (17449) Traceback (most recent call last): File "/usr/local/mailman/Mailman/Queue/Runner.py", line 110, in _oneloop self._onefile(msg, msgdata) File "/usr/local/mailman/Mailman/Queue/Runner.py", line 160, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/local/mailman/Mailman/Queue/IncomingRunner.py", line 130, in _dispose more = self._dopipeline(mlist, msg, msgdata, pipeline) File "/usr/local/mailman/Mailman/Queue/IncomingRunner.py", line 153, in _dopipeline sys.modules[modname].process(mlist, msg, msgdata) File "/usr/local/mailman/Mailman/Handlers/ToDigest.py", line 91, in process send_digests(mlist, mboxfp) File "/usr/local/mailman/Mailman/Handlers/ToDigest.py", line 132, in send_digests send_i18n_digests(mlist, mboxfp) File "/usr/local/mailman/Mailman/Handlers/ToDigest.py", line 306, in send_i18n_digests msg = scrubber(mlist, msg) File "/usr/local/mailman/Mailman/Handlers/Scrubber.py", line 265, in process url = save_attachment(mlist, part, dir) File "/usr/local/mailman/Mailman/Handlers/Scrubber.py", line 361, in save_attachment fnext = os.path.splitext(msg.get_filename(''))[1] File "/usr/local/mailman/pythonlib/email/Message.py", line 714, in get_filename return unicode(newvalue[2], newvalue[0] or 'us-ascii') LookupError: unknown encoding: X-UNKNOWN
