Some providers are Rejecting Mails whith wrong configurated DNS. Every Provider is handling by self... But the best way is when you are configurate your DNS include the Reverse Zone... Some Providers and Firewalls are checking the Reverse Zone entries. When you have forgot to programm it you can have big trouble...

Postfix rejects mail with "reject_unknown_client", even when a ptr record exist, but forward and reverse lookup are not identical. In our logs we see this misconfiguration happen very often. When I activate blocking these clients, the reject rate nearly doubles. Just want to know, how you deal with this. Do you reject mail from clients with misconfigured dns or do you tolerate it? Regards and have a nice weekend.
