Hi Michael,
You can set Scrubber.py not to use the orginal filename in the message
by adding followin line in mm_cfg.py (mailman-2.1.6 and above).
SCRUBBER_DONT_USE_ATTACHMENT_FILENAME = True
Developers,
May be we should set this default in Defaults.py.in in the next release
of 2.1.7. Thoughts?

Resolved. The digest keeps a seperate mbox file at
{MMDIR}lists/LISTNAME/digest.mbox removing the email from that location
was the solution to my immediate problem.
This does expose a DOS attack potential for MM lists. The too long
attachment name needs to be handled in a more graceful manner.

Update:
I've found the offending message and purged it from the list archives,
purged it from the shunt files, and purged it from everywhere I could
find it.
Yet the problem persists. So I'm looking for the temp file/mail area
where the file that contains this attachment may be found.

I have a list that was sent a file with an attachement with too long a
name. (See error below) now all mail to the list is being shunted.
the filename listed does not exist on my system. There is no file on my
system with that name.
The directory
/var/lib/mailman/archives/private/rca-l/attachments/20051207/3d04c3a4 is
empty.
What do I need to do to resolve this problem?
