Postfix installation HOWTO

SpamAssassin modules - Perl modules

SpamAssassin is a mail scanner that analyses text and uses several internet-based lists to block/identify spam messages. It doesn't block emails only rewrites original messages and adds a tag ( level spam ) so you can filter messages on your local PC. SpamAssassin detects mail between 95% and 99% of cases. Also, it may use Razor databases to identify spam.

Requirements

Modules that are required but usually come with default Perl installation:

    File::Spec >= 0.8  
    ExtUtils::MakeMaker >= 5.45
    Pod::Usage >= 1.10 
    Sys::Syslog

Also we need to install extra modules as shown below:

    perl -MCPAN -e shell
    install DB_File
    install Net::DNS
    install Mail::Audit

Pyzor

Checks messages' signatures the Pyzor collaborative filtering network. Pyzor requires at least Python 2.2.1. At our example we used Python 2.3 To install this software download the latest version from https://sourceforge.net/project/showfiles.php?group_id=50000 and install as shown below:

    bunzip2 pyzor-*.tar.bz2
    cd pyzor-*
    python setup.py build
    python setup.py install
###    chmod -R a+rX /usr/local/share/doc/pyzor 
###    chmod -R a+rX /usr/local/lib/python2.3/site-packages/pyzor 
###    chmod -R a+rX /usr/local/bin/pyzor 
###    chmod -R a+rX /usr/bin/pyzord

In regular case if you need not your own signature server you can use public servers of Pyzor network.

Razor

Used to check message signatures against Vipul's Razor collaborative filtering network. Download it from http://razor.sourceforge.net/ and install as usually

    tar -xzvf razor*
    cd razor*
    perl Makefile.PL
    make 
    make install

DCC (Distributed Checksum Clearinghouse)

DCC (Distributed Checksum Clearinghouse) is a system similar to Razor. It checks fuzzy checksums and therefore detects some more spams than Razor does at the moment. To install this software, download http://www.rhyolite.com/anti-spam/dcc/source/dcc-dccproc.tar.Z and perform the following steps:

    tar xfvz dcc-dccproc.tar.Z
    cd dcc-dccproc*
    ./configure && make && make install
    cdcc 'info'

If you have it installed successfully you should see a lot of text and one of line should have something like following:

	dcc.rhyolite.com,-         RTT+0 ms    anon
