After upgrade to the RC12 no more time limit exceed in postfix log, but in the deliver log, I have:
Error: User request from dovecot-auth timed out
How can I improve the performance of the dovecot-auth ?
Can I use the dovecot-auth cache ? It's disable in our configuration ?
If the deliver is giving such timeouts, then I'd guess that you'll get similar problems for pop/imap logins as well.
What passdb and userdb are you using? auth-cache might help, but I'm guessing the problem is that you're using some blocking passdb/userdb which causes the whole process to hang while waiting for a reply from somewhere.
How many dovecot-auth processes do you have? The default is one (auth section, count=1). Growing that might help. How large is the CPU usage by the dovecot-auth?
