NAME
    spamproxyd - mail filter to identify spam using text analysis

SYNOPSIS
    spamproxyd
OPTIONS
        spamproxyd currently has no options.

DESCRIPTION
    IMPORTANT! PLEASE read CHANGES.spamproxy before continuing!

    This is a prototype for an SMTP filter based on Mail::SpamAssassin
    (http://spamassassin.org, http://spamassassin.sourceforge.net).

    This was originally written with Postfix's filering in mind, based on
    the "advanced" example detailed in the FILTER_README file in the Postfix
    distribution, but there's no reason why it couldn't be used with other
    servers.

    This script is just proof of concept right now; it may more than likely
    not be usable in a larger-scale environment where there's high volumes
    of mail being transferred. However, it's currently good enough for a
    small-scale environment, like the IRC network for which I serve as
    postmaster, along with several other people I service on a small
    machine.

    This script requires Mail::Assassin (see above) and Net::SMTP::Server
    (http://www.macgyver.org/software/perl/, plus it is also in CPAN). You
    also need a modified version of one of the modules in order to connect
    to a specific SMTP server, which I include in the package.

    Right now, this script has a couple of shortcomings:

    1. Configurability, configurability! This is especially true if this
    will filter for multiple people whose needs may be quite different,
    including per-user weighting of the "suspicious stuff", white-lists,
    etc, and of course, whether to tag spam then deliver (if wanted), even
    whether to filter at all.

    2. What do YOU want? Who knows? With Perl, your imagination's the limit.

    So far, I've managed to zap quite a bit of spam that'd normally go right
    through the server. With Vipul's Razor, this can go up quite a bit. If
    anyone has any ideas about Vipul's Razor and how I populate my arrays,
    please let me know.
