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'});

good luck!
