Released Copfilter 2.0.91beta2

There was added some new options to C-ICAP and updated some perl modules.


If you plan to update from previous copfilter release and update your IPCop to 2.0.3, you should at first

create a backup of your Copfilter settings. After them uninstall Copfilter, ugprade IPCop to 2.0.3 and then

install Copfilter 2.0.91beta2. Reboot your IPCop, afterwards restore your Copfilter settings, check or change

your settings and restart all services on Copfilter status page.


For C-ICAP users, you should know that you have to install the C-ICAP integrated squid binary again,

because of a squid update. You have to enable C-ICAP explicit, because of some new options are avaliable.

Please download and install the security fix for Copfilter v1 & Copfilter v2

Released Copfilter 2.0.91beta1


Copfilter 2.0.91beta1 comes with some new improvements, new addons, a revised gui, revised shell output

and in additional some bugs has been fixed.

The most important change is the new integrated C-ICAP filter, which comes with a virus filter and an

urlfilter for HTTP traffic. Note: The C-ICAP URL-Filter is no replacement for the SquidGuard based URL-Filter,

integrated in future IPCop versions!

It is recommended, to read the C-ICAP URL Filter HowTo on the footer in C-ICAP gui settings, which also

contains an illustrated description.
Spamassassin now use the shortcircuit function for black- and whitlist handling

In additional, the most popular 3rd Party sigs from Severus has been integrated.

If you plan an update from previous copfilter release, please deactivate monit before uninstall previous Copfilter release!
After new Copfilter install, reboot your IPCop machine for taking changes in effect (this is especially needed for

Imspector users)!

ClamAV Antivirus databases are downloaded during the installation.


The disabling of the local anti-virus scanner is no longer necessary because the test virus is now encrypted!

Released copfilter-2.0.90beta4


(this is the first post by karesmakro)

I'm not a man of big words, but I want to introduce myself. I'm an around the clock admin who supports companies with their system- and network environments and also assembles/installs their servers (all in Linux). Since I benefit much from open source software (knowledge), I want to give something back to the community. That's why the Copfilter project became my hobby. 


As Markus already mentioned, I was working on a copfilter release for upcoming IPCop v2 version and I think it is stable enough now and ready for publishing. I want to say thanks to Markus for his confidence and his effort in me and I will try to keep this project in honor of!


My special thanks goes also to Severus and FischerM (and all that were not listed here) from the copfilter forum, who supported Copfilter over the long years with their effort and improvements to this piece of software and who helped to keep this project alive!



Note: The copfilter-2.0.90beta4 Version is only a prerelease, until IPCop 2.0 stable has been published!



2010 12 21 23:40 (by Markus)

Released copfilter-0.85.2


  • removed the "score FH_DATE_PAST_20XX 0.0" entry in (is fixed in SA 3.3.1)
  • activated SA plugin "Mail::SpamAssassin::Plugin::AWL"
  • removed the ! on line 578 in setup_util
  • replaced my perl_modules with the ones from kares spamassassin package (they were more complete)



2010 12 21 20:30 (by Markus)

Since I do not use Copfilter anymore personally, I have decided to stop most of my active work with Copfilter.

But no worries, I will slowly handover the future Copfilter development to karesmakro, granting him full access to the sourceforge project as well as to this Website/Wiki/Forum. Kare has provided the Copfilter community with frequent updates - like ClamAV and he is currently working on a version for the next IPCop release. I will still be around as a project maintainer by providing/maintaining all the infrastructure (Wiki, Forum, Website), maybe some parts of Copfilter and by having a voice whenever major design decisions are to be made.


2010 12 15 17:55

added a flattr button to the website to allow micro-payments


2010 12 04 23:22 

copfilter-0.85 still has a problem with some perl modules, so for example bayes training via imap is not working correctly. We are working on a fix. copfilter-0.84beta4 does not have this problem.

FischerM created most of the content of the new official copfilter wiki! Thanks! 

2009 12 09 15:52 
The new official copfilter forum is online. Unfortunately all old data is lost. Since I am now maintaing the forum myself, this should not happen again. I will soon start working on an updated copfilter version. 

2009 12 09 14:39 
Unfortunately all data from the copfilter forum is lost. I will now setup and maintain my own forum to ensure that this does not happen again. Will post here as soon as the forum is ready. 

2009 12 03 17:37 
The copfilter forum is down and I cannot tell what happened or when it will be up again. Maybe all forum data is lost. I will post more as soon as I have figured it out. 

2009 03 04 09:58 
Please use this patch from forum user karesmakro to fix a bug where the main ipcop page will not show the ipcop hostname and ip address after installing copfilter-0.84beta4.tgz.

2008 07 08 07:22 
It has been a very long time since the last update. This is because I was very busy with the university I am attending. My studies are not over yet, but since a few copfilter users asked on how they could speed up the development and also made some donations, I now feel even more obligated to at least update the included programs. So its time to tell you that I am indeed working on a new version (with the great help of some copfilter forum users) with the latest program updates. No date yet, but it will be available as soon as it is finished.

Today my studies at a local university will begin (in 6h 51min 8-) which will mean that I can't dedicate 
all of my spare time to Copfilter anymore, my responses to the forum or via email could also take a bit 
longer than usual :-(   BUT of course I will still try to do my best 
for example currently I'm trying to to implement greylisting and hopefully resolve these bugs soon 
Even though development, bug resolving and responses etc might eventually become slower 
I will still go on with Copfilter :-))
