MIME::Lite and smtp auth

[Qnick]

Hello,

I want send mail with attachments through smtp server with
authentication. I found script which use Mime::lite and added
authentication:

MIME::Lite->send('smtp', $host, Timeout=>60
AuthUser=>$user, AuthPass=>$pass);

as CPAN says, but don't act properly. Server reject the message.


Thanks very much indeed for any advice or pointers to useful
information.

Regards

Qnick
