Consider the line below in an ACL acl_smtp_rcpt section:
require verify = recipient
It's my understanding that the above ACL line tests the recipient
address during SMTP time to see if it is valid. I believe that means
the address is passed through the routers.
If I am correct, and I have the following very simple router:
faileverthing:
driver = redirect
allow_fail
data = :fail: nothing is allowed to get through
The response to the RCPT smtp command will be a 5xx error, right?
If I don't include the "require verify = recipient", the message will be
accepted (assuming no other ACL's decline it) and returned to the sender
as a bounce message once it hits this router in the processes after SMTP
acceptance. Correct as well?
Thanks,
Terry
