That the server is slow or difficult to manage [which includes backup] is the issue - not that it uses MBOX [regardless of that its use of MBOX is the root of the *server's* issue]. Thinking of it in terms of messages-storage-format is misguided [I only mention it because I see the MBOX/MH/Maildir/Maildir++/etc... debate frequently]. This represents, IMO, a flawed approach to the problem. Migration to a new solutions [an IMAP server] that provides better performance / management is the fix. Incidently, it will almost certainly not use MBOX. If you are 'manually' crawling around in your message-store [the *only* case where you'd actually care much about storage format] indicates something else it wrong [as well].
