How about pop-before-smtp? Would I add the check_client_access immediately after permit_mynetworks above? Will this configuration above prevent DSL or cable users without reverse, only forward DNS from being accepted? I keep receiving the following: Nov 1 15:34:42 smtp01 postfix/smtpd[28620]: warning: 67.142.235.122: hostname host6714200122235.direcway.com verification failed: Host not found The IP is in the popb4smtp db, but they still receive a relaying denied message: Nov 1 14:32:44 smtp01 postfix/smtpd[23790]: reject: RCPT from unknown[67.142.235.122]: 554 <j...@mydomain.com>: Relay access denied; from=<joe3...@inside.mydomain.com> to=<j...@mydomain.com> Thanks so much.
