Hmm, that doesn't look different from mine. <br />
<br />
The log message you get shows that unix_chkpwd is called to verify the<br />
given password and that again means that all the mail users have to be<br />
stored in /etc/passwd and /etc/shadow.<br />
<br />
Jan 12 11:25:41 hermes unix_chkpwd[4601]: check pass; user unknown<br />
<br />
Can you su - $USER (if the user has a valid login shell)?<br />
<br />
