Rejecting email based upon MAIL FROM:, RCPT TO: and From: values

[Konstantin Boyandin]

Hello,

I need to possibly reject mail, in case the below is all true
- domain part of From: header and RCPT TO: addresses is the same
- domain part of MAIL FROM: differs from domain part of From: header

Looks like I need to use filtering via check_policy_service; question 
is, into which Postfix restriction directives shall I add such a 
condition?

Thank you.

Sincerely,
Konstantin
