I don't want to sound like some "use anything but Perl"-guy ;), but the easiest solution would be to pipe the output to `mail` (mailx or Mail), since the output is already printed to the screen. Example:

$ your_perl_script.pl | mail -s "Output from your_perl_script.pl" user
+@domain.com
[download]

Please note that I assume you run the script on some *NIX platform...

Update: Linked to the wrong node - fixed
