I've been tasked to figure out a way for our three postfix relay servers to intercept every hard bounced back
e-mail and process it for our web application.
We have about nine servers relaying mail through our three postfix servers. These servers send mail on behalf
of our clients. I'm trying to figure out a way to intercept a hard bounce back from the destination server
and process it internally instead of bouncing back the error to our clients. I've figured out a way to have a
copy of the bounce that would have gone to the postmaster account and have that get processed, but it would
have still bounced it back to our client as well.
I was looking into VERP but I would need to modify the smtp servers to include "MAIL FROM:<sender at domain>
XVERP" in the header. Since these are Windows servers that are sending the mail, I'd rather not have to do that.
Is there any other method that would work to suppress sending out the bounce backs and have a program that I
wrote process them instead?
