Spam protection detects and prevents unwanted viruses, including emails, from entering your inbox. Spam filters run each email against thousands of predefined algorithms. Each algorithm has a numerical score that defines the chances of an email being spam. When it crosses this threshold, the email is tagged as spam and blocked from entering the inbox. The different types of spam filters include content filters, header filters, rule-based filters and blocklist filters. There are various benefits of spam protection:
- Only pass the most legitimate emails to the user’s inbox
- Prevents malicious content, compromised website links, and phishing attacks
- Saves bandwidth
- Audits and archives emails without direct user intervention
- Provides access control to take actions against the sender or receiver
- Prevents data leakage
A business email system without spam protection becomes highly vulnerable to potential risks, phishing attacks, and viruses.
