What methods are there that I can check if STARTTLS is working? I have tried openssl s_client -connect mail.mydomain:587 -starttls smtp and it comes out correctly (all the certificate thingy shows and I did a EHLO mail.mydomain.com and got back all of the correct 250 responses including AUTH PLAIN LOGIN....but when I try and connecting to my mail server via Thunderbird, Roundcube, or my phones mail app it doesnt work so something is wrong here.
What other ways can I debug whats wrong? The maillog isn't showing anything really.
EDIT: Ran that command again, did EHLO mail.mydomain.com and then tried AUTH usernamehere and I got 535 5.7.8 Error: authentication failed: so there is something wrong with AUTH it seems..
