Can you advise an alternative mail software to use and how I would use it in the below script?

use strict;
my $sendmail  = '/usr/lib/sendmail -t'; 

open (MAIL,"|$sendmail") || "Not working: $!";

print MAIL <<"EOF";
To: smith\@here.com
From: jones\@here.com
Subject:  theSubject

Information here etc
EOF

close MAIL || "Not working: $!";
