Ok, so... I'm *still* unclear, and please understand I'm not trying to
be difficult, but I want/need to understand this. One thing not helping
is I don't have a working dovecot setup I can access to go peek at the
filesystem, which would probably let me answer this for myself.
When you say 'commonly fetched fields', can you confirm this means it is
simply the number of emails that can cause the problem?
Is this index file kept on a per *folder* basis? Or per user/account?
If it is per folder, then it is much less of a problem, and could be
worked around simply by moving messages around (say, archiving).
