Cleaning up IMAP flags or what have you

["JJ" <ding_gnus.org@sumou.com>]

Gnus has messed up my IMAP mailbox, I think. By messing with the evolving
state of Gnus these past couple of months, something has happened to my
mailbox, which has resulted in Gnus setting all my mails to Unread, i.e.
now I have 2476 items unread in the INBOX, but not in its subfolders.

Furthermore, this would not be such a problem, as I can set them all to
read from Gnus.

However the biggest problem is, that it doesn't check the number of unread
articles now, i.e. when running Gnus, I get all the subscribed INBOX
groups and INBOX itself with a star on the left of it.

`g' has no effect, i.e. says connecting, but then `No Gnus is good news'
and the star stays.
`M-g' updates the INBOX to the correct two-k something of unread messages.

but it doesn't last, i.e. after quitting Gnus and restarting, the count is
a star again.

But it doesn't do this with a test account that I've created on the same
server and sent three messages to, so it shouldn't be a prob with the
server config...

What could be the problem and how can I "reset" the maildir so to speak,
so that it works normally?
