[Dovecot] Dovecot SASL vs. Micro$oft Outlook and Outlook Express
Hi, I have just started using Dovecot (1.0.10) SASL behind my Postfix (2.3.3). Everything works fine, as long as I send the SMTP AUTH command manually. When using M$ Outlook (2000 and 2003) and Outlook Express 6, authentification always fails. Turning on the Dovecot auth debug on reveals the reason: Dovecot SASL expects, in accordance with the standards, the following format of the SMTP AUTH command (using the PLAIN auth mechanism):
AUTH PLAIN base64_encode("username\0username\0password")whereas the M$ clients send as the second argument only base64_encode("username\0password"), which naturally leads to authentification failure. Postfix apparently does not play any role in this game, as it simply passes the received command arguments to dovecot.
Before I start hacking the source myself, I just wanted to ask if somebody has a patch for this M$ shortcoming - as the damned M$ clients are very much spread, I would assume this should be the case...
Thanx, --- Tom

Before you started hacking the source, it would probably be a good idea to at least try the latest version first.
I think Timo is preparing to release rc16, but rc15 is the latest...

Might be a good idea, but as I see no difference between rc10 and rc15 in the auth/mech-plain source, I doubt it will help...

I don't know about a patch per se but I am using rc15 and postfix 2.3.5 w/ dovecot sasl enabled in postfix. I had to add "login" mechanism to dovecot.conf in order for outlook variants to work.
auth default {
mechanisms = plain login
. . . }

Yep, that was in the end the problem - Outlook and Express do support PLAIN only for IMAP, not for SMTP. Including the LOGIN mechanism was the solution, sorry for not reporting before.
