That is how sendmail works. That is how sendmail has been
designed. For sendmail, Perl is overkill.
I am not interested in discussing other MTA's here.

For sendmail, the sendmail binaries reads the rules, and does
the rewrites. Everything that sendmail does is a rewrite rule, with
function calls as part of the replacement. Using Perl is not an
option anyway, and having sendmail parse Perl regular expressions is
a bad idea.
Sendmail provides just enough functionality in the regular
expressions to be suited for the task at hand.
