As blakem points out, you usually want to use a local SMTP server and let it worry about getting the mail to the correct place, but if you want to do this yourself you need to employ DNS; specifically looking up of MX records, which -- as luck would have it --Net::DNS's (alt.) mx method can help ...

use Net::DNS;
my @mx = mx("perlmonk.org");
