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.
