Betreff: [exim] BATV and SRS interaction
Regarding how SRS interacts with BATV tagged envelope senders.

If an originating sender is BATV tagged, but then the receiving host forwards to a third host. How does the forwarding host handle the BATV tagged address if it were to SRS rewrite it? Seems like one or the other, BATV or SRS would break.

Possible workaround, but not fixes by any means would be to:

1) Forward the envelope sender as is with if it’s BATV signed. Mean SPF would not pass on the final destination

2) Remove BATV tags and rewrite with SRS. Meaning bounces to the original sender would break.


Or am I missing something and that BATV and SRS re-writes co-exist in harmony? It certainly does not seem possible?
