I want to know how a double bounce can be captured in MS Exchange. A double
bounce is created when a bounce bounces on its way back.
No sane MTA sends a NDR in response to a NDR, or to any other DSN.
NDR's, indeed all DSN's, are sent with the "null" address "<>".
Undeliverable NDR's should be dropped by the receiving MTA.
Typically, both the
sender and recipient addresses are invalid.
That should create a single NDR to be sent to the sender.
In Qmail and Sendmail, this task
can easily be achieved by modifying some configuration parameters.
I haved been looking for same kind of admin control parameters in the MS
Exchange, but could not find anything relevant yet. Any help would be
appreciated.
If you're asking how to collect the NDR's that can't be delivered,
Exchange 2000 dumps those into the "badmail" directory. Exchange 2003
SP1 stops that behavior. If you want to collect those undeliverable
DSN's, read this:
The Badmail folder is disabled in Exchange Server 2003 SP1 [884068]
But that begs the question why you're accepting mail you can't
deliver. Why not just refuse to accept undeliverable mail and make you
life a lot easier?
