Postfix smtpd_client_restrictions
Keeping known email abusers out is always desired. Postfix has a parameter which is specified in the main.cf file that allows you to refer to these lists. The script I use is as follows...smtpd_client_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_pipelining reject_rbl_client cbl.abuseat.org reject_rbl_client dnsbl.ahbl.org reject_rbl_client dnsbl.sorbs.net reject_rbl_client list.dsbl.org reject_rbl_client sbl-xbl.spamhaus.org #reject_rhsbl_client blackhole.securitysage.com reject_rhsbl_client rhsbl.sorbs.net permitNote the commented out line
#reject_rhsbl_client blackhole.securitysage.comThis is a list that was not properly administered. A friend of mine tried to email me who uses the mac.com domain and was being rejected as an abuser which, of course, is rediculous. I keep the entry as a future reference. There are others out there so if you know of them please let me know. mta.
