Don't use "reject_unknown_client" uncondionally. Use it selectively in a check_client_access cidr:/etc/postfix/client_access.cidr rule that subjects "high-value" CIDR blocks (lots of junk with no reverse mappings in a block, with some legit clients "mixed-in" whose PTRs are valid), for example: 192.0.2.0/24 reject_unknown_client -- Viktor.
