POP3 Virus Scanner Proxy is a full-transparent proxy daemon which scans all mails for viruses using third party scanners (built-in support for AVPD and Trophie).

You have to set up a port redirection in the linux-netfilter (iptables) so that all connections from e.g. inside your office to any POP3 server outside in the world will not leave your router, but come a local port, on which POP3VScan listens. POP3VScan receives from the linux kernel the original destinations of packets (the POP3 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 neccessary parts of the POP3 protocol and when an email is sent from the server, we store it into a file, invoke a virusscanner and send it if it is good, or we just replace it with a virus notification. It should be possible to use all scanners using the scannertype=basic. Also POP3VScan provides scannertype=avpd for high-speed scanning using Kaspersky Anti-Virus for Linux, every C programmer can easily adept other scan-daemons (trophie, sophie, antivir, ...).

Neither the client nor the server has to be configured, none of them will take notice that theres a mailscanner (except the client when he gets a virus notification or if he looks into the header, and the server gets our ip as source).

Viralator is a Perl script that virus scans HTTP/FTP downloads request on a UNIX server after passing through the Squid proxy server.
Even when I implemented virus protection for my network email server we still continued to get the odd virus. Most of the viruses came from people using free webmail accounts like Hotmail or Yahoo and downloading the infected attachments to their machines or through downloading junk.
Rather than block access to the users I decided to look at how we could better protect the network. I looked at a couple of different products both comercial and free but they were either too expensive or did not meet my needs.
That is how Viralator was born. Viralator Proxy Virus Scanner is licenced under the GPL.
Viralator should work in any UNIX system that uses Apache and Squid servers. We have reports about successful instalations on:
- RedHat Linux
- Mandrake Linux
- SuSe Linux
- e-Smith Linux
- Slackware Linux
- Conectiva Linux
- Debian Gnu Linux
Supported Redirectors:
- Squirm
- SquidGuard
- Jesred
Supported Virus Scanners
- AntiVir
- AVP
- RAV
- Inoculate
- Sophos Sweep
- McAfee
- Trend
- Clamav
- Bit Defender (free edition)
The original concept for Viralator came from the Viromat project. Without Viromat the Viralator project would not have had a starting point. We can also thank Ralph Meyer for badgering me into releasing the script under the GPL.
Enhancements:
- Parenthesis are included on the regular expression used to validate URLs.
- The character set checking step, which was not working before last patch released, has been fixed.

gadoyanvirus is a virus checker for qmail that works with the QMAILQUEUE patch by Bruce Guenter. gadoyanvirus scans incoming messages using the ClamAV anti-virus library.

Suspected messages are quarantined and a notification message can optionally be sent to the recipients.

The Qmail virus scanner (QScan) is a mail filter for Qmail that scans incoming messages using the Sophos Antivirus engine, immediately rejecting infected content.

It is designed to be minimalistic, yet extremely fast and secure, and uses multiple pipes instead of the traditional temporary files and privilege separation. It works with non-native versions of the virus scanner like under OpenBSD with Linux or FreeBSD emulation.


You must create a temporary directory to extract MIME attachments, and replace Qmails original qmail-queue program with Qscan. Quick way to achieve this for the impatients :

mkdir /var/qmail/qscan
chmod 700 /var/qmail/qscan
chown qmaild:qmail /var/qmail/qscan
ln /var/qmail/bin/qmail-queue /var/qmail/bin/qmail-queue-old

Now, lets compile and install Qscan :

./configure --help

./configure [your beloved flags]

make install-strip

The last step is to replace the original qmail-queue program with our filter :

rm /var/qmail/bin/qmail-queue
ln -s /usr/local/sbin/qscan /var/qmail/bin/qmail-queue

Depending on your local configuration, it may be needed or not, but start with doing it :

chown qmaild:qmail /usr/local/sbin/qscan
chmod 6711 /usr/local/sbin/qscan

After testing, if everythings ok for you, remove the setuid bit :

chown 0:0 /usr/local/sbin/qscan
chmod 711 /usr/local/sbin/qscan
