So I should have known better. I upgraded to 8.3. *sigh* Now it seems that Qmail is slow to respond for my main domain and fails to deliver messages on any new domain. I do not use mailboxes. All email is forwarded. I've run the mchk without any luck. I've also tried installing the mysql client libraries as I found in this thread. I do have mysql 5.x installed. I don't see anything odd in the /usr/local/psa/var/log/maillog. The server isn't using much cpu or ram. OS is Fedora Core 6. Any ideas?
