    Best way to allow RFC 2298 compliant out-of-office responses


      Some of our external business partners have enabled "out-of-office" responses but those responses are dropped by our Ironmail server.



      I understand that these are considered RFC-2298 Message Disposition Notifications.  As such, they have no "from" address.


      20111128:16:11:21|5821359|9988|Sending domain not available, From address is: -||





      What is the "best" way to allow these responses to not be dropped?  For this one sender I have whitelisted the IP addresses.   I to find a more generic way to allow these compliant messages to not become dropped by Ironmail.
