SpamAssassin and Amavisd: Go Ninja On Your UBE Woes
Building a Better GatewayThe bad news is, it's SpamAssassin, not SpammerAssassin. The good news is it kills spam quite effectively, and fits nicely into an anti-spam, anti-virus gateway. This article, which shows how to use SpamAssassin with Postfix, is the first in a series on building an anti-spam and anti-virus gateway. This gateway works equally well for a single PC, or for a large network, and it's built of four components:
Prerequisite: An existing Postfix server, that is running well and happily. The other bits are add-ons to Postfix. They work just fine with other mail transfer agents (MTAs) (define) like qmail, Exim, and Sendmail, but this series will center around Postfix.
But I Don't Run Windows
That's all right, you will still benefit from this. You can probably omit Clam Anti-Virus, and just use SpamAssassin.
I Confess, I Run Windows
If you run any Windows hosts, then by gosh you absolutely need this, every bit of it. Before investing time and energy in building this anti-spam/anti-virus gateway, do take some elementary precautions:
- Outlook Express
- Internet Explorer
Replace them with any of the following fine free email clients and Web browsers:
- Eudora Mail
- Pegasus Mail
- Mozilla/Netscape Mail
- Opera Mail
- Opera Web Browser
- Mozilla/Netscape Web Browser
You have now closed off the major malware ports of entry, and can move on to the next steps.
