Compile IPFIREWALL into your kernel. Have a look into /etc/rc.firewall: Make a rule to deny access from the evil domain to your IP on port 25 (that's the SMTP-port). Enable firewalling in /etc/sysconfig Install new kernel. Reboot. Have a look at "man ipfw". Further, try to talk to the Provider of this domain. Darius Moos. Timothy P.
