[Users] Dovecot 2.2.34 can break your world

If you're using Claws-Mail as a window into your local Dovecot IMAP
server, when you get bumped up to Dovecot 2.2.34 is going to break your
world. Claws will tell you something like "handshake error".
The root cause is that Dovecot 2.2.34 dropped support for SSLv2, so any
SSLv2 in your config breaks Dovecot. But I'm pretty sure that even if
you don't specify an SSL version, 2.2.34 defaults to SSLv2 (which it
dropped support for), so you need to manually write in uncommented SSLv3
in 10-ssl.conf everywhere commented SSLv2 occurs.
Cranking up the log levels in 10-logging.conf help in diagnosis, as do
openssl s_client -connect 127.0.0.1:993
If you use Dovecot as an IMAP for Claws and stuff stops working,
remember this email.
