Postfix reject_unknown_client

• Interesting topic about filtering. Enforces proper records A and PTR in DNS. I'm whitelisting some IPs, but I stopped when the sender has unresolvable HELO string. Enough!


• Postfix on IRC lives, but on mailing list has an advantage: there is Duchovny - he responses redirecting to Postfix documentation, but responses. IRC looks like a group of quite people. They drunk probably, pizza boxes lie on the floor ;-)


• Chart rejected-spam-ham works. We are trying munin.
