Steinar,

I've investigated and reported this bug before.  "Holey" mailboxes
like you describe will trigger it.

    The root cause seems that when UID SEARCH UID fails, nnimap ends
    up deleting/expiring all articles involed in this UID SEARCH UID
    command.  UID SEARCH UID seems to fail on large lists of
    sequences.  In Exchange case "large" is pretty small :-), but I've
    seen similar problems on very large "holey" mailboxes on uw-imapd.
