P3Scan Description

EditBy This is a full-transparent proxy-server for email clients. It runs on a Linux box with iptables (for port re-direction). It can be used to provide email scanning from the internet, to any internal network and is ideal for helping to protect your "Other OS" LAN from harm, especially when used in conjunction with a firewall and other Internet Proxy servers. It is designed to enable scanning of incoming/outgoing email messages for Virus's, Worms, Trojans, Spam (read as "Un-solicited Bulk Email"), and harmfull attachments. Because viewing HTML mail can enable a "Spammer" to validate an email address (via Web bugs), it can also provide html stripping. You have to set up a port redirection with iptables so that all connections from e.g. inside your office to any POP3/POP3S/SMTP server outside in the world will not leave your Router, but come to a local port, on which P3Scan listens. P3Scan receives from the Linux Kernel the original destination (the email server outside in the world) and will connect to them. All data we receive from the client will be sent to the server, and vice versa. With a little enhancement: we parse the necessary parts of the protocol and when an email is sent from the server, we store it into a file, invoke our scanning, and send it along if it is good, or in the event of POP3/POP3S we Replace It with a virus notification and optionally delete the infected message. For infected SMTP messages, we reject the message.
