Hi Keith,

Well, that depends on which authentication fails. If this is during SMTP 
auth, you need to go through your sasl and tls settings in postfix, as 
well as your sasl conf file. For me this is 
/usr/local/lib/sasl2/smtpd.conf, but your environment may be different.
If this indeed is an SMTP authentication problem (not POP3, not IMAP4),
you need to study this: http://www.postfix.org/SASL_README.html

Here is a bit more information...

SMTP-AUTH is handled by postfix (which runs it through the SASL 
authentication routines depending on your SASL setup).
POP3 and IMAP4 AUTH are handled by your respective POP3 and IMAP4 
daemons. This authentication processes has nothing to do with postfix.
The thing that they *should* share in common is authentication *data*. 
For instance, on my server, the SASL, IMAP and POP authentication all 
look to the same mysql table for user account and password information.
It is important to test each piece of software (POP, IMAP, SMTPwithSASL) 
separately. Once you are sure that each one is authenticating and 
allowing services properly, THEN you can work on making sure that they 
work TOGETHER properly as well.
