I'd still be very surprised if this ends up being a Mailman problem.
Python strings don't care at all about end-markers, NULs, etc. so you
can't put something in a string that would cause Python to shorten
it.  And Mailman just uses the file object's read() method to suck the
message in from disk, and that just reads the whole file.  On writing,
Mailman will hand the whole string over to the smtplib module, which
itself just blasts the whole thing down the socket connection.

I'm much more suspicious of the MTA or some other intermediary
bolluxing something up.
