Richard Valk maintains a set of step-by-step instructions for making your Mac into a full-blown web, mail and more server.

Today he has released a walk-through for adding dspam , an open-source spam and content filtering system to the mix.

So now, following his guide, you will not only end up with:

a Mac which you can use to host your and your friends web sites by using an Apache2-based web server which uses PHP 5 and can talk with a MySQL 5 database. This means you can install most PHP/MySQL based applications like for instance blogs or forums like Wordpress and phpbb. You are also able to provide mail services for them with unlimited mailboxes, domains and web-based email services using Roundcube.

But it will be spam-free as well (well, 99.5-99.95% spam-free is all dspam actually claims).

Nice.
