This is the old way of accessing your sendmail program directly. It is generally frowned upon by Perler's, but it usually works. (on win32 your mail program may be called "blas", IIRC 
#!/usr/bin/perl
use warnings;
use strict;

my $mailprog ="/usr/sbin/sendmail";
my $mailflags ="-t -n -oi";
my $recipient = 'recipient@domain.com';
my $msg_goes_here = "you're message";

open  SENDMAIL, "| $mailprog $mailflags" or warn $!;
print SENDMAIL "From: user\@domain.com\n";
print SENDMAIL "To: $recipient\n";
print SENDMAIL "Subject: testing 123\n\n";
print SENDMAIL $msg_goes_here;
close SENDMAIL;
