I assume you mean '96? Perl wasn't around in 86, let alone Perl
And in '96 Python already had a basic email handling
Batteries included etc.

Probably, although you might decide to do it in raw C...
But seriously the Pythonic route is to use the module not the
regex. regex's are used heavily in Perl because its so good at
them, but they are just not used as often in Python because
there is often an alternative approach, usually involving a
parsing module of some sort...
