I setup a mail server using followings components

postfix
sasl
pam-mysql
courier-auth 0.58
courier-imap 4.0.6
mysql 5.0.16

email user is authenicated against mysql backend db
I added a test account in db and I tested the smtp auth and it works (i.e.
can authenticate against db)
but I failed to test with imap and pop3

Turn on authentication debugging for more information. See
http://www.courier-mta.org/authlib/....authdebug.html

Then report back here what's in your debug logs after turning this on.

Problem solved. It's directory permission problem.
