Hello, SMTP authentication does not work at all for me and I can't send messages if I can't SMTP AUTH to my SMTP server on each and every mail. I'm running this : Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1b) Gecko/20020721 Symptoms : I check the "Use Name and Password" in the smtp settings. I enter my login code to the SMTP server. When I attempt to send messages, Mozilla don't even ask me (as the help says it should) for my password. And I immediately receive a refusal from my server which does not allow the smtp session to go further without authentication. So I can't say that Mozilla does not support this or that SMTP AUTH method (my server gets LOGIN and CRAM-MD5) : I think it don't even try to authenticate as it don't even ask me for my password... That's a show-stopper (for me). -- Olivier Mascia

Tested also with latest win32 build today (2002072608), same problems. I have not yet found a single SMTP server (accessible by me) where the AUTH would happen with Mozilla. It is not a server issue.

I'm adding this a dup of bug 25974, which explains that you have to set a special preference first. If it doesn't work with you, please report in bug 25974. And I would complain about the lack of GUI, if I were you. *** This bug has been marked as a duplicate of 25974 ***
