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
