I did grep the perl source - version 4.036 - for Mail, and found only
one hit:

perl-4.036/emacs/tedstuff:Sender: mmdf@uvaarpa.Virginia.EDU (Uvaarpa Mail System)

You have to grep for "mail", or more precisely, "/bin/mail".  Or, to
perhaps save you the time, it's in perl.c (perl-4.036/perl.c, at least
for this version).
