The migration is done so far.

There is again a new SSL cert for IMAP/POP, fingerprints[1].

Note: The INBOX namespace (which came from courier) has been disabled
so you may have to fix some subscriptions in your mail client.
E.g. INBOX.Drafts is now just "Drafts".

There is also sieve/managesieve support, you can enable it by using
| "/usr/libexec/dovecot/deliver" in your .forward [1].
This will disable procmail of course but it will also improve the
performance/speed.
