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.
