1) There are no "e-mail programs" written in Perl... You need to have a mail server installed
2) There are hundreds of different scripts written in Perl that can handle sending and receiving e-mails...
Do you need to be able to just send, or receive as well? Do you need to be able to attach files? What about HTML formatted e-mails? What about address books? ...etc.
BTW....I don't spam....I'm just interested in sending the email to the individuals that request it.
Thanks for your time.
