[Dovecot] dovecot.org moves to a new server

Parts of dovecot.org will be down for a few hours while I'm moving to a new server (and to a new ISP as well). The new server won't be virtual anymore, so I'm hoping to get a bit better performance from it as well (the old virtual server had some disk I/O hogs). The DNS records have been using 1 hour TTL for last few days, so this move should be fast for everyone.

Thanks to Nebula for hosting dovecot.org for the last 7 months.

So, beginning the move by shutting down Postfix and Mailman..
