[Dovecot] postfix-dovecot-sasl help

[Ted To]

I'm trying to set up SMTP authentication on my server and am getting an
authentication failed error.  My client is set up to automatically
select authentication method and tries CRAM_MD5.  The
http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL suggests "passdb
pam" and "userdb passwd" -- is it possible to configure sasl
authentication using a dovecot.conf like http://pastebin.com/6JWE5jp1?

Thanks in advance,
Ted To
