"Lookup timed out" really shouldn't be happening.. That sounds like
Dovecot's MySQL connections hangs after a while? You have some stateful
firewall between Dovecot and MySQL that drops idling connections and
afterwards starts dropping the connection's packets?
Indeed, there is a firewall with stateful inspection between Dovecot
and MySQL. The only workaround is a downgrade to Dovecot 1.1.20. I
think my problem has to do with the changes in
src/auth/auth-worker-server.c in changeset 8859.
