reject_unknown_client_hostname (with Postfix < 2.3: reject_unknown_client) 
Reject the request when 1) the client IP address->name mapping fails, 2) the name->address
mapping fails, or 3) the name->address mapping does not match the client IP address. 
This is a stronger restriction than the reject_unknown_reverse_client_hostname feature,
which triggers only under condition 1) above. 
The unknown_client_reject_code parameter specifies the response code for rejected requests
(default: 450). The reply is always 450 in case the address->name or name->address lookup
failed due to a temporary problem.

In der Standard Einstellung  kommt nur ein 450er code temporärer reject.


Mit freundlichen Grüßen
