Yes. This does indeed solve most problems, but not all. I guess the main
problem is that nnimap-update-unseen, on which the above fixup function
depends, is only called upon closing a group. I remember that I still
had situations where I got wrong unread article counts, but I can't
currently reproduce this with dovecot.

I still wonder why there are so many problems with the Zimbra imapd
server. It must have to do with how Zimbra generate UIDs for the
articles. Dovecot and most other imap servers at least try to keep them
contiguous.

Anyway, the fixup function only deals with unread articles, but I think
we should also fix the problem of the total article count. Many people
(including me) have the problem with Gnus thinking that a group contains
much more articles than there actually are. This can currently only be
solved by respooling.

I wouldn't use it in the current form, but I think we should follow the
general idea, i.e. using gnus-request-group-articles (which is already
there).
