Install Pyzor

Download pyzor from Sourceforge (https://sourceforge.net/projects/pyzor/files/latest/download).

# wget https://sourceforge.net/projects/pyzor/files/latest/download

Unpack the package:

# tar xf download

Move into the dir [Documentation]:

# cd pyzor-0.7.0

Pyzor requires at least Python 2.6

To install this distribution, simply run the following:
       python setup.py build
       python setup.py install

Note that your system might install the modules and scripts
with non-world-readable permissions.
Correct this with a command such as:

       chmod -R a+rX /usr/share/doc/pyzor \
               /usr/lib/python2.2/site-packages/pyzor \
               /usr/bin/pyzor /usr/bin/pyzord

To use the server, the Python gdbm module or MySQLdb module is required.
You can generally check if you have the gdbm module by executing:
       python -c 'import gdbm' && echo 'gdbm found'
You can generally check if you have the MySQLdb module by executing:
       python -c 'import MySQLdb' && echo 'MySQLdb found'

The gdbm module is available at:
       Debian GNU/Linux:
               http://packages.debian.org/stable/interpreters/python-gdbm.html
       Gentoo Linux:
               Will be built with Python if the gdbm library is found.
               If it isn't there with your Python, try stealing
               the FreeBSD setup.py patchfile in their ports to
               install just the gdbm module, or simply re-install
               Python.
       FreeBSD:
               ports/databases/py-gdbm
       tar.gz:
               included in the Python distribution
               (not sure of the precise procedure for simply installing
               the gdbm module; try stealing the FreeBSD setup.py patchfile
               in their ports).

Pyzor also works with Python3.3. The code will be automatically refactored with
2to3 during the setup:
       python3.3 setup.py install

Note that the MySQLdb library does not currently support Python3.

See docs/usage.html for usage documentation, and if you are upgrading
from another version of Pyzor, please read the UPGRADING file.

The 'pyzor discover' command tells pyzor to contact home and find the latest list of servers to use. I add this to a cron to be run nightly:

17 2 * * * pyzor discover

Make sure that pyzor is enabled in your /etc/mail/spamassassin/v310.pre file:

# Pyzor - perform Pyzor message checks.
#
loadplugin Mail::SpamAssassin::Plugin::Pyzor

And then make sure that spamassassin is going to use Pyzor as a check:

echo "use_pyzor 1" >> /etc/mail/spamassassin/local.cf

Now check to make sure it shows. Note: You will frequently show a timeout on Pyzor. This is normal - the server is very busy.

spamassassin -D --lint

And that's it.

Some more tips for Pyzor:

The default server will timeout 50% of the time. Google to find another server to use - most do NOT allow high volume servers to check against theirs. If you find some that DO allow this, please post them here for the rest of us!
