Then, at this exactly mail server machine:


# nslookup 209.85.219.66

Please don't use nslookup. It has inherent flaws.


So, postfix is complaining that "cannot find your hostname", but the reverse DNS is working just fine. Any clue!?


reject_unknown_client_hostname will reject clients that fail the complete IP -> PTR -> IP lookup.

If this is not what you desire, limit it to reject_unknown_REVERSE_client_hostname only.
