Spam Filters: Protect Your Inbox

The Spam Problem

Spam emails waste time and can contain malware. Good filtering is essential.

How Do Spam Filters Work?

Content Analysis

Suspicious words and patterns are detected.

Sender Reputation

Known spammers get blocked.

SPF and DKIM

Verification that an email really comes from a legitimate server.

Spam Filtering in Plesk

Plesk offers built-in spam filtering with SpamAssassin.

Whitelist and Blacklist

Add trusted senders to the whitelist. Permanently block unwanted senders.

False Positives

Sometimes legitimate mail ends up in spam. Check your spam folder regularly.

Setting Up DMARC

Extra verification that prevents spoofing of your domain.
