If you have an SMTP account, you could look into Net::SMTP, which has worked nicely for me many times.

#!/usr/bin/perl -w

use strict;
use Mail::Sender;

#create mail and send attached a file if you want
$sender = new Mail::Sender{
               smtp => 'smtp_server_of_your_mail',
               from => 'my_name@whatever.com'
              };
$sender->MailFile({
           to => 'name@whatever.com',
           subject => 'Hello....',
           msg => "The attached file i've been trying to send....hmmm"
+,
           file => 'my_file.foo'
          });
$sender->Close();

Mail is not something to mess around with.. as the world can attest to with the gobs of spam floating around the world. That being said, it is expected that if you're going to play with sending mails yourself you should know what you're doing.

Perl has ActiveState PPMs for the Mail::Sendmail module, and you can find these at http://search.cpan.org/~mivkovic/Mail-Sendmail-0.79/Sendmail.pm (search cpan for Mail::Sendmail).

Mail::Sendmail is a great simple module for sending your email to a SMTP server, and you will almost certainly have access to one with your ISP account wherever that is. IE if your isp is myinternet.com, then odds are you can send your mail to smtp.myinternet.com, which will take care of forwarding your email appropriately to the destination SMTP server.

Bypassing this process and performing the mail agent operation yourself is a risky and difficult process, something recommended for the experts. I have played with sendmail and believe me it's not a simple job.

I know I'm not being helpful here, but I recommend you become a guru in SMTP and mail in general before getting Perl involved in such advanced tricks..
