I have configured an open relay with a line like below in /etc/tcprules.d/tcp.smtp:
88.88.88.88:allow,RELAYCLIENT="",SENDER_NOCHECK="1",QMAILQUEUE="/var/qmail/bin/simscan",NOP0FCHECK="1" I've re-compiled simscan for spamassassin check on relayed messages, is there any way to block a particular e-mail address to relay messages (not only domain name, an e-mail address like u...@domain.com should be blocked which is hosted on 88.88.88.88)?
