If you are verifying incoming recipient addresses, they get rejected at
SMTP time, and it is the remote sending MTA that generates the failure
report. At the present time, the SMTP error that Exim sends is "cannot
route to <address>". If the far end is a sensible MTA, it should include
this text within the message it generates. However, I don't suppose all
of them do.
As an aside, it seems like a good idea to extend the prohibition_reason
mechanism (which currently applies only to policy rejections only, not
"normal" verification failures) to include this case too. I have noted
this.
If you are not verifying incoming recipient addresses, you can add a
smartuser director at the end of your directors to send undeliverable
messages to a pipe or autoreply transport that generates a suitable
message, tailored as you like. Or you can make use of the errmsg_text
and/or errmsg_file options.
