Description - Copfilter 0.1.0 beta for IPcop

The main goal of Copfilter is to provide a free and easy to use solution to filter and scan traffic
from any unsecure network, like the internet, for viruses and spam. It has been designed
as a preconfigured and easy to install addon for the opensource firewall IPCop

Copfilter is a package of various opensource traffic filtering software and tools, customized and built to work
together. All included proxies filter traffic transparently, which means that no client reconfiguration is necessary.

It scans POP3 and SMTP emails for viruses and spam. Instead of a virus infected emails, a user will receive virus
notification messages containing details about originally sent emails, which can also be quarantined if desired.

Spam emails will be tagged as spam by inserting the following text into the subject field: *** SPAM ***
With this procedure any email client will be able to use its own message rules to
automatically delete or move these spam messages.

HTTP and FTP traffic will also be scanned for viruses. If a virus is found, access to that web page or file will be denied.

      Glad I'm running copfilter. I clicked on a web e-mail today and it was 
      blocked as a phishing attempt. Way cool!

      Hi Markus
      I had the same problems w/copfilter as described by others in this thread. 
      I made the edit to the file as you requested - on two different machines 
      so far, about 18 hours ago - and all of the problems have vanished.....
      Copfilter is the best - fabulous piece of software!!
      Great work!!
