Re: postfix smtp authentication

[Serkan Hamarat <serkan@efes.net.tr>]

Seems confs are okay.  Look also authentication log files under
/var/log/ .  I hope it gives a clue.  i remember that it must be
log/auth.log or it writes in log/syslog file.

Try to add an 'acct' line to your pam.d/smtp file :
auth required pam_unix.so
acct required pam_unix.so

Finnaly; try to uninstall libsasl2 and libsasl2-modules-plain or 
something like version 2 sasl, if you use stable.
