Using the Search bar (up on every Perlmonks page), I come up with Mail attachments, Sending attachments with Sendmail and How do I send an email with Perl (including an attachment)?. Have a look at these.

They all use modules to send mail, mostly MIME::Lite from what I glance.

We really need a forced search on anonymous postings that searches each topic line for "similar questions" ...

This is a frequently asked question around here. Had you bothered to use Super Search, you would have found a large number of discussion on this subject. The advice you'd get from all these nodes is "use the MIME::Lite module or the MIME-Tools bundle of modules - get them from CPAN".

I've been using Mail::Sender on both Windows and Unix, and it works just fine. An example from the man-page:

use Mail::Sender;
$sender = new Mail::Sender{
             smtp => 'smtp.server.com', 
             from => 'your@address.com'};

$sender->MailFile( {
              to => 'some@address.com',
              subject => 'Here is the file',
              msg => "I'm sending you the list you wanted.",
              file => 'filename.txt'});

Wow Mail::Sender is incredibly easy to use, I got it working after 2 min including the:
perl -MCPAN -e shell
install Mail::Sender
I recomend trying it first.
