Ooh.  There's nothing good about that.  He wants to snoop all connections
to /any/ mail servers originating on his network?  This is a total ethical
minefield.  Maybe he should just block 25, 110, and 143 and have done.

If he really must snoop all this mail you could grab it off the wire as
you have been and pipe it into procmail, which would deliver it to a mail
user.  And he could view it with his favorite MUA.  This link might help:
