Hi there, we are running Qmail and Spammers are using our SMTP as a relay. We've configured our sistem as it is at: http://www.palomine.net/qmail/selectiverelay.html, where we have on tcp.smtp : [root@correos /etc]# cat tcp.smtp 194.179.87.:allow,RELAYCLIENT="" 195.76.4.:allow,RELAYCLIENT="" 195.76.5.:allow,RELAYCLIENT="" 195.76.107.:allow,RELAYCLIENT="" and we start tcpserver with : env - PATH="/bin:/usr/bin:/usr/local/bin" \ /bin/sh -c "ulimit -m 8192 ; \ exec tcpserver -x/etc/tcp.smtp.cdb \ -c60 -g500 -u20001 0 25 /var/qmail/bin/qmail-smtpd" & and on /var/qmail/control/rcpthosts we have listed all our domains hosted. But when we put all this together, users can't use our SMTP as relay, but our users can't either if they send to a domain not listed on our rctphosts. If any body can help... Ray
