This is your problem. Your UID has gotten higher than 2^31 which
confuses many clients, even though it's still valid from IMAP protocol's
point of view.

As for why it has gotten this high.. Well, recent Dovecot RCs could
break them sometimes, but at least with 1.0.rc27 everything should be
working.

If you remove the X-IMAPbase, X-IMAP and X-UID headers and delete
Dovecot's index files the messages will be given new UIDs beginning from
1.

If this just keeps happening, then I think it's because the incoming
mails contains invalid X-UID headers. Normally those shouldn't break
anything as long as you haven't deleted Dovecot's index files or the
mbox file isn't empty. If they do and you can figure out how to
reproduce it, please let me know.

Anyway, the problems would most likely go away if you just filter out
all the X-UID headers from incoming mails. See the bottom of
