SMTP traffic filter on FreeBSD 7.0 gateway
Hello,
I have a question about ways to filter smtp traffic that passes from LAN through FreeBSD 7.0 machine (configured with NAT and gateway="yes" in /etc/rc.conf) to the Internet.
I've installed both SpamAssassin and ClamAv, and now need the software that would listen to port 25 on private IP address. I think it would be something like Squid Web proxy
I have read about smtp-gated, assp, but i think that this software is for use with configured mail server and not for my purpose
Thanks in advance
