Hi,
Is it possible for Exim to verify outgoing mail when using a smarthost?
Specifically, I'm looking to have Exim verify (using dnslookup) that the
domain exists for the recipient. If the domain returns NXDOMAIN (or some
other DNS error), defer it, if DNS exists, continue with the routing. I
tried the following:
# Verify the recipient domain exists in DNS before sending to the relay.
verify_address:
debug_print = "R: verify_address for $domain"
driver = dnslookup
domains = ! +local_domains
verify_only
no_more
