Sever the clutches of Spam on Linux mail servers

In today's world, Spam continues to be rampant and increasingly a serious problem because spammers are becoming smarter, so preventing spam is a necessity for anyone running a mail server. For organizations using Linux, there is now an outstanding tool for preventing spam: Spamassasin. Now let's take a look at how to curb spam through spamassasin.

Know SpamAssassin

Spamassasin is a mail filter that uses a range of mechanisms to validate spam, including text analysis, Bayesian (Bayesian rule) filters, lists of DNS blocks, and collaborative, misplaced databases. Spamassasin does not delete junk e-mail, but it can block spam. The main reason is that it has the following characteristics:

Wide range of activities: Spamassasin uses a large number of local and network tests to identify spam features. This makes it more difficult for spammers to make clear the usability of the information they manufacture.

Free software: As with other popular Open-source software (such as Apache Web Server), it is distributed under the same conditions.

Easy to scale: anti-spam testing and configuration information is stored in plain text, which makes it fairly easy to configure and add new rules.

Flexibility: Spamassasin encapsulates its logic in a well-designed, abstracted API, so it can be integrated anywhere in the e-mail data stream. Spamassasin can be used in a variety of e-mail systems, including: Procmail,sendmail,postfix, qmail, etc.

Easy to configure: Spamassasin requires little User configuration. You do not have to constantly update the Spamassasin configuration with the membership details of your email account or mailing list. Once categorized, site and user rules can be shipped to spam. And the rules can be applied to mail servers, and in the future you can use your own mail user agent application.

Spamassasin is often considered one of the best spam filters. This article will guide you through the installation, configuration, and use of this powerful tool.
