[Mailman-Users] PGP keys causing problems

[Jeff DeReus]

Hello,
I am running mailman 2.1.5 with sendmail.  One of my users sent in an
attachment with a message to the list.  When he signs with his PGP key, only
the PGP signature remains in the message.  I have yet to locate the rest of
the message.  It is necessary to disable the signature to allow his posts to
go through properly.  Is there  a method to allow for secure signatures on
messages?  I have searched quite a bit and have yet to find relevant
information.  Any information/assistance would be greatly appreciated.

Thank you,
Jeff D
