G'day fellow postfix junkies!
I can get postfix to reverse name lookup IP addresses.
postfix "Reject clients with no reverse hostname" does not find reverse hostname for any IP address. I can check host names on IP address from the command line ok, but postfix doesn't seem to find any. Blocks all emails.
I get the feeling postfix might need a missing setting on where to resolve hostnames to IP addresses.
Tearing my hair out!
Any Assistance much appreciated,
