When that happens, we’re pattern-matching: our brains have learned to associate specific words, phrases, typography, and grammar with unwanted email. We know what it looks like, and, usually, alarm bells start ringing in our minds even if we can’t say precisely why. We all receive spam and can recognize what it is right away. What Is SpamAssassin and How Does It Work?
To make sure we understand how it works, let’s take a close look at what SpamAssassin is, how it works, and the best settings for SpamAssassin in cPanel. Apache SpamAssassin flags spam to remove it before it gets to users. If you host email, you need a way to identify and filter unwanted messages, and cPanel integrates one of the most sophisticated filtering tools available.
Still, hundreds of billions of messages are sent every year by automated botnets that collect email addresses, compromise servers, and bombard users with malicious advertising and phishing attacks. The good thing is ISPs and hosting providers are better at stamping out spammers, and users are more aware of the risks. Most unwanted messages never reach inboxes, but an incredible 54 percent of all email traffic is spam, and that’s down from 70 percent a decade ago. Spam is a huge challenge for anyone who hosts email, even though users only see a tiny fraction of the spam they’re sent.
