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.
