[Mailman-Users] Content boundaries vanish from mime messages ininput queue

Mark, et al.,
Hi. This is a source install that I've been using for a long time
mostly for locally generated messages and digests, but am now using
for large numbers of externally generated (moderated) message
distributions. I should add that I also have removed (including all
white space -- and I set the configuration default for both to "")
the headers and footers for direct distribution (I've left in the
header for digests, on the assumption that won't be an issue). I
had *thought* this had solved the main problem, and I have a test
message that apparently came through correctly, but later tests are
failing again. I feel like the guy in the old movie "The 4D Man" who
kept trying to replicate the one time his tricky experiment worked.
What's happening is that messages coming through (and they look this
way in the moderator's preview as well) are being stripped of all
MIME boundaries -- I'll include an example below. The boundaries
are clearly present (and the messages display correctly) on cc'd
versions that don't go through mailman. During testing, I also had
an incident where it appeard that a newly arrived test message was
deleted unseen when a bunch of older messages were being deleted thru
the moderator interface, but I'm not ready to swear to that yet.
Example of the Mime problem follows. Note that the crypto portion
immediately follows the main text with no boundary, nor is there
a boundary at the end of the crypto section. Any ideas appreciated!
