The prog mailer is generally for aliases that pipe mail into programs
-- eg:

   msgs: "| /usr/bin/msgs -s"

It's not often used --- too much opportunity for abuse over the
network.  About the only thing I remember ever using it was majordomo,
but I suppose it could be something to do with anti-spam or anti-virus
scanning.

The question now must be why your system is using the 'prog' mailer to
do final delivery of your e-mail?  Got any interesting entries in
/etc/mail/mailertable or /etc/mail/aliases ?

	Cheers,
