Well in perl you simply open up a pipe, so you can do more in perl than
you can in PHP with the mail() command.

Not only that, but why not just provide a special header so that we can
provide this functionality transparently on all systems, or, if its just
sendmail that has problems with it, detect whether or not we are using
sendmail (which we do on all *nix and BSD systems, if I'm not mistaken),
if so, replace the header with the -f command to sendmail.
