We have been noticing intermittent messages of this sort and
wondered if this indicates whether we need to add more dovecot-auth worker
processes:

Mar 28 03:15:41 myhost dovecot: pop3-login: Can't connect to auth
server at default: Connection refused

This change should help with these (rc28):

Auth worker processes anyway don't matter here, the connections are
accpted by the master dovecot-auth process. You could increase them
from count setting inside auth block, but I'm not sure if that could
cause other problems.
