I've tried 2 builds of dovecot, based on a amd64 rebuild of the
experimental package on http://xi.rename-it.nl/debian/
I've tried to include as much useful info as possible, sorry if I've
missed out anything of use. Let me know as I'm more then happy to
assist in any way possible.
$ telnet host 110
Escape character is '^]'.
+OK Dovecot ready.
