write a policy server (or use one that implements this). postfix checks use a single variable (client, helo, sender, recipient). you can't mix things.

I'll try this way.
 

anyway, if you find yourself whitelisting many clients, then you should abandon the check. reject_unknown_client is unsafe. even if the client has a correct rNDS setup, the check will delay mail if there is a dns lookup failure. while testing it, I noticed that it delayed mail from dspam and netbsd mailing lists.

I'll investigate.
 

if your goal is to fight spam, there are safer and more efficient checks. you should start with zen.spamhaus.org.

Thank you guy.
