Re^3: Net::SMTP - Connection to local MTA refused

ok, i may be missing something here, but dont modern mail senders require you to authenticate first? ie:

$l_mailer->auth($smtpuser, $smtppassword);
[download]

before

$l_mailer->mail($p_sender);
[download]

That would be necessary if the form mailer sent its data through the submission port (587/tcp). However, I'm sending this through port 25 which doesn't require authentication (it's normally used so that other MTAs can connect, but localhost is allowed to send there, too).	[reply]
