anyone familiar with courier-imap and courier-imap-pgsql combination, i just installed 
it via rpm and i 
end up not able to connect imap server. here's what i get from /var/log/main/info

...

i did some googling and i was able to read documents about SASL?! it says that SASL 
will play the role 
of passing "auth" variables to pam, which i believed pass that information to pgsql 
for authentication of 
smtp users. talkin' about SASL, is Cyrus-SASL compatible for 
Courier-imap/Courier-imap-pgsql 
implementation? and... do i really have to enable TLS? is it required for postfix and 
courier-imap?

btw, here's some settings:

/etc/pam.d/imap
auth       required     pam_nologin.so
auth       required     pam_stack.so service=system-auth
account    required     pam_stack.so service=system-auth
