I already replied to this in IRC, but for others too:

JFS doesn't update directory's mtime when files are added, removed or
renamed in it. So Dovecot can't know when the maildir has changed
without constantly reading its contents. With Linux's dnotify this could
be kind of worked around, but I'm not really interested about doing
that.
