From: Dennis Carr on
I just set up basic configurations for SMTP AUTH (and, the next step,
SASL) for my server, however I cannot seem to make it work quite
right. Using the instructions at, focusing on using dovecot as
it is present. (Note, dovecot is not the active POP3/IMAP4 daemon,
that seems to be deferred to the basic daemons from xinetd.)

On testing, this happens:

$ telnet 25
(motd and dialog involving EHLO goes here)
535 5.7.0 Error: authentication failed: authentication failure

The only thing I noticed is that Dovecot did not
place /var/spool/postfix/private/auth, which from what I'm reading of
the instructions, should happen.

What am I doing wrong here?
