FYI,
I have changed the warnings from the code that implements
forward-confirmed reverse DNS (FCRDNS).
When the "reverse" name has no IP address:
hostname foo.example.com does not resolve to address 1.2.3.4:
host not found, try again
When the "reverse" has some address but not the expected address:
hostname foo.example.com does not resolve to address 1.2.3.4
The old warnings were very different.
1.2.3.4: hostname foo.example.com verification failed: host
not found, try again
1.2.3.4: address not listed for hostname foo.example.com
That's in both smtpd(8) and qmqpd(8).
