Read through the thread. No it didn't help. I change the filebase,
ignore to filebase, ext like the thread indicated but I still end up
with the same thing. The problem is the mailman handles the file name
and the fact that users are using long file names. Its not a problem
with the extention as I thought. Mailman drops the last part of the
file name off, so a file name like this:
PRESIDENT'S NEWSLETTER NO. 2 - 2003-2004 ACADEMIC December.pdf

Becomes a file name like this:
PRESIDENT'S NEWSLETTER NO. 2 - 2003-2004 ACADEMIC

So the December.pdf part is lost. I've verified it is not a MUA
problem by running tests in debug mode and checking what got sent to
Mailman. It is in the attachment handling routine of mailman that the
problem exists.
