For simple mailing do something like:

my $mailer = "/path/to/mailer";
open(MAIL, " | $mailer") || die ("Can't open PIPE to mailer: $mailer (
+$!)\n");

print MAIL <<'EOF';
To: you@yourdomain.com
From: "The Camel" <your_perl_script@domain.com>
Subject: This is your camel speaking!

This is a mailbody, spoken by your camel, wearing a red-hat,
being friends with penguin, called Tux

EOF

close(MAIL);

For maintainability you might want to decide to place the 'heredoc' (<<'EOF' ... EOF) outside of your code.

If you are about to do really great things with these emails, (such as adding attachments, etc.) you might want to read in to the use of the modules available on CPAN.

This code is untested, yet believed functional
