Pyzor is a completely free database and software HashSharingSystem, written by Frank Tobin. http://pyzor.sourceforge.net/ .

Install Pyzor

...

• See the installation instructions at InstallingPyzor. Do not simply follow the instructions at the Pyzor siteBe sure to run "pyzor discover" after you install Pyzor, so that you can download the server to contact.

Using Pyzor Site-wide

• Note permissions advice concerning /etc/mail/spamassassin in RazorSiteWide and add the following to your /etc/mail/spamassassin/local.cf: pyzor_options --homedir /etc/mail/spamassassin
  • Now put some servers in that dir: pyzor --homedir /etc/mail/spamassassin discover
  • And finally, restart spamd: /etc/init.d/spamd restart

Is it working?

You can run SpamAssassin from the command line to figure out if it is using Pyzor. The process is described at RazorHowToTell, but the summary is to run the following from the command line:

  echo "test" | spamassassin -D pyzor 2>&1 | less

This test should return output similar to:

...
Oct  6 11:11:46.956 [10904] dbg: pyzor: network tests on, attempting Pyzor
Oct  6 11:11:52.055 [10904] dbg: pyzor: pyzor is available: /bin/pyzor

Oct  6 11:11:52.345 [10904] dbg: pyzor: check failed: no response
...

The "check failed: no response" does not indicate a problem, as this test does not pass in an actual properly-formatted email message. If you have an actual message handy, use that for your test; you should see output similar to:

• Download and install ActivePython from www.activestate.com.

• Download and install Pyzor from http://pyzor.sourceforge.net/. You'll need something that can un-bzip2 the files. Installing simply means running the following from the folder you extracted pyzor into:

  No Format
  python setup.py build python setup.py install

  
  

• Create a folder somewhere for the pyzor config files. You can use your spamassassin folder if you like as it only creates a single file called servers. I used c:/python24/etc/pyzor

• Create a pyzor.bat in your python folder (c:\python24 by default when I installed it), containing the following line, modified for your python folder path.

  No Format
  @c:\python24\python c:/python24/scripts/pyzor --homedir c:/python24/etc/pyzor %1 %2 %3 %4 %5 %6 %7 %8 %9

  
  

• Edit /Lib/site-packages/pyzor/client.py with the following changes:
  • Find signal.signal(signal.SIGALRM, handle_timeout) and put a # in front of it.

  • Find the section for: def time_call(self, call, varargs=(), kwargs=None): and change it to read like this:

    No Format
    def time_call(self, call, varargs=(), kwargs=None): if kwargs is None: kwargs = {} return apply(call, varargs, kwargs)

    
    

• From a command prompt in the python folder context, run the following where /python/pyzor is the folder you created in the previous step.

  No Format
  pyzor discover

  
  

• Now you are ready to configure SpamAssassin to use it.

• (This is not necessary in v3.1.7) Edit your /site/lib/mail/spamassassin/Util.pm. Find the "sub helper_app_pipe_open_windows" section and the line that reads

  No Format
  if ($stdinfile) { $cmd .= " <'$stdinfile'"; }"

  and replace it with

  No Format
  if ($stdinfile) { $cmd .= " <\"$stdinfile\""; }"

  because Windows won't pipe a file with a space after the < and single quotes around it.

• Edit v310.pre and uncomment the load for the Pyzor plugin.

• Edit your local.cf and add configuration lines for pyzor. For example:

  No Format
  use_pyzor 1 pyzor_path c:\python24\pyzor.bat pyzor_timeout 10

  
  

• That should do it. If you do a spamassassin --lint -D you should see pyzor
