      Hello i created an etc/postfix/postscreen_access.cidr in my postfix
      dir.
      now postscreen checks on connect for the entries.

      i set one server in the list with reject

      Is it right, that the test mail goes thru postfix?

      i see in logs :

      Sep 27 16:43:30 netcogw postfix/postscreen[15206]: CONNECT from
      [78.46.56.1xx]:31558
      Sep 27 16:43:30 netcogw postfix/postscreen[15206]: BLACKLISTED
      [78.46.56.1xx]:31558
      Sep 27 16:43:30 netcogw postfix/postscreen[15206]: PASS OLD
      [78.46.56.1xx]:31558


      do i have to clear any special cache before to test if 78.46.56.1xx
      gets blocked?
