Indeed, there is a firewall with stateful inspection between Dovecot
and MySQL.
Right, so the "Lookup timed out" works as intended. But I guess it
should automatically retry when that happens. There would still be that
1 minute delay before that happens though.
The only workaround is a downgrade to Dovecot 1.1.20.
Wonder what v1.1 does differently. I can't think of anything, really.
The main fundamental problem is still that mysql connection hangs and
the hang can't be detected/avoided. I think the right fix here would be
to change your firewall settings..
I think my problem has to do with the changes in
src/auth/auth-worker-server.c in changeset 8859.

Yep.
