Timo, Thank you for updating the MainConfig web page.
This is what I decided to put in for that value. Currently dovecot runs about 4 days before it starts to fail authenticating users. I did a quick count on how many times auth-worker is called to authenticate a user, I'm averaging about 50K times a day (M-F). So I'm putting in 20,000 for the "auth_worker_max_request_count" so that it only restarts the dovecot-auth process 2 or 3 times each day. If anyone else has better suggestions for this value, I'd would love to hear it.

The lower it is, the more CPU Dovecot uses by restarting the dovecot-auth processes. But if it's too large, you'll get these failures. So I don't know, try 1000?
The http://wiki.dovecot.org/MainConfig doesn't talk about this config parameter.
That's generated from dovecot-example.conf. Looks like I forgot to update it to be generated from v1.1, changed now. Wonder how I'd remember to do the same thing after v1.2.0 is released. :)
