No it does not return any mails, although there are mails older than 90 days in
the INBOX.

I copied over the mails with rsync from the old mailbox server to the new one.

Did you add sufficient flags to rsync to retain file mtime and ctime? These are
used to determine the mail saved date.

I have been using "rsync -av". As far as I know the "-a or
--archive" parameter should preserve almost everything, at least the rsync
man page says that.
