The only way I could think of for doing this would be to create a
second set of mailer definitions with the 'M=' (Maximum message size)
setting altered appropriately, and custom parsing rules to force the
messages sent from a particular address to be delivered via those
mailers.  Needless to say, that's going to be a pig of a job to set up
and configure correctly.  You would be better off setting up some sort
of Milter or indeed forcing all of the messages to be processed
through procmail(8).

See or for somethings that might
do the job -- except that apparently neither of those can filter by
message size.  Both are available in ports -- if the term 'Milter'
means anything to you, and you're fluent at C programming then adding
a check on message size might be possible.
