Hello,<br><br>I recently installed dovecot1.0rc25 on my RHEL4 system running postfix and wish to use both virtual and system users. Virtuals work fine, but I get authentication failures with system users. I've tried pam, passwd and shadow.  

Attempting to telnet as system user telnet localhost 143 Trying 127.0.0.1... Connected to localhost.localdomain (<a href="http://127.0.0.1">127.0.0.1</a>). Escape character is '^]'. * OK Dovecot ready.
