mail/p3scan is a fork of mail/pop3vscan, a transparent POP3 virusscanner

	P3Scan is a transparent POP3-Proxy with virus-scanning
	capabilities.  This means that all your POP3-Clients in the
	Network can't fetch mails from the internet without that
	P3Scan have scanned it. If a virus has been found the mail
	is replaced with a notification and the original (infeceted)
	version is stored on the harddisc. Transparent means, that
	neither the client nor any of the used POP3-servers has to
	be configured.

	This port is based on mail/pop3vscan, but the development
	for that port seems to have ceased.

+By default, POP3VScan is configured to work with McAfee UVSCAN.
+Please copy PREFIX/etc/pop3vscan.conf.sample to pop3vscan.conf and modify
+PREFIX/etc/pop3vscan.conf and/or PREFIX/etc/rc.d/pop3vscan.sh to
+fit your environment.
+
+Don't forget to copy PREFIX/etc/pop3vscan.mail.sample to pop3vscan.mail
+and edit your own template for virus notifications.
+
+By the way, you need to enable IPFIREWALL and IPFIREWALL_FORWARD options
+in kernel, and add the forwarding rule into your IPFW table,
+
+# ipfw add fwd 192.168.0.254,8110 tcp from 192.168.0.0/24 to any pop3
+
+while 192.168.0.254 is the IP of your internal interface, 8110 is the
+default port of POP3VScan, and 192.168.0.0/24 is the IP range of your LAN.
