[mess-mate]

Hi,
i upgraded from rc1without ldap.
I can login and i see my boxes, but they are empty
(Of course they are not.)
I'm running courier-imap on the server.

Also having this problem, a long with many more.
I wonder if anyone actually reads these boards. I have never had one of my bug reports acknowledged!
