Fully transparent proxy server for POP3 clients

'p3scan' is a fully transparent proxy server for POP3 email clients. It runs on a GNU/Linux box with iptables (for port re-direction). It can be used to provide POP3 email scanning from the internet, to any internal network and can help protect your "Other OS" LAN from harm, especially when used with a firewall and other internet proxy servers. 'p3scan' is designed to enable scanning of incoming email messages for viruses, worms, Trojan horses, Spam (read as "Un-solicited Bulk Email"), and harmful attachments. It can also provide HTML stripping to keep spammers from validating email addresses (via Web bugs).
