Hello, I built and installed courier 0.54.2 RPMs on Fedora Core 6. I then setup the authentication system to use MySQL, and setup a virtual domain with the maildirs living in /home/mail/ [domain.com]/ [username] I created a courier user (503) and a courier group (503), chowned the entire /home/mail structure to courier:courier. I also configured the record in the passwd table for uid=503 and gid=503. Despite all of this, when I attempt to login to any of these accounts, I get the following entries in the log: Feb 18 14:08:27 mountaineer imapd: Connection, ip= [::ffff:<filtered IP address>] Feb 18 14:08:31 mountaineer imapd: kevin@<domain name filtered>: chdir(/home/mail/<filtered domain name>/kevin) failed!! Feb 18 14:08:31 mountaineer imapd: error: Permission denied Feb 18 14:08:31 mountaineer imapd: LOGIN FAILED, user=kevin@<filtered domain name>, ip=[::ffff:<filtered IP address>] Feb 18 14:08:31 mountaineer imapd: authentication error: Permission denied I have filtered out the IP address and domain, but rest assured that I have verified that the paths exist as configured, and the permissions are appropriate. What on earth could I be missing?
