If it has to be postscreen, you can setup a local RBL lookup and score it high enough to trigger a rejection. But based on your pattern, there are RBLs already out there that will block those sorts of patterns. You can also setup a file like rdns.pcre And check it via check_reverse_client_hostname_access pcre:/etc/postfix/rdns.pcre But that will not be postscreen. An RBL like zen would be better. -- On nights such as this, evil deeds are done. And good deeds, of course. But mostly evil deeds. --Wyrd Sisters
