The Exchange server is not my problem(tm).

If you're saying that exchange is losing the mail, the easiest fix is to
configure postfix as a relayhost between the outside world and the
broken exchange server. Postfix will queue the mail and send it to the
exchange server as quickly as possible and if the exchange server is
down, it will wait until it's back up again.
If you're saying that there is actual broken client software (Outlook,
etc.) that's "loosing" mail, why not configure it for IMAP instead of
POP so the mail will remain on the Exchange server?
