Spam blockers for emails

The eternal struggle against spam emails! Here are some effective spam blockers for emails:

  1. SpamAssassin: An open-source spam filtering system that uses a combination of rules and machine learning to identify and block spam emails.
  2. Bayes Spam Filtering: A statistical approach that uses Bayesian probability to classify emails as spam or not spam. Many email clients and servers, such as Mozilla Thunderbird and Postfix, support Bayes filtering.
  3. Greylisting: A technique that temporarily blocks unknown senders and requires them to resend their emails after a short delay. This helps to filter out spam emails that are sent from open relays or compromised accounts.
  4. DNSBL (Domain Name System Blackhole): A system that uses DNS records to block emails from known spam sources. Many email providers and servers use DNSBL to filter out spam emails.
  5. Spam filters built into email clients: Many email clients, such as Microsoft Outlook, Mozilla Thunderbird, and Apple Mail, have built-in spam filters that use a combination of rules and machine learning to identify and block spam emails.
  6. Third-party spam filtering services: Services like SpamAssassin, SpamSieve, and SpamFilter offer advanced spam filtering capabilities and can be integrated with your email client or server.
  7. Content filtering: Some email providers and servers use content filtering to block emails that contain specific keywords, phrases, or attachments.
  8. IP blocking: Some email providers and servers use IP blocking to block emails from known spam sources, such as open relays or compromised accounts.
  9. Machine learning-based spam filtering: Some email providers and services, such as Google's Gmail and Microsoft's Outlook.com, use machine learning algorithms to analyze email content and identify spam emails.
  10. Human moderation: Some email providers and services, such as ProtonMail, use human moderators to review and block spam emails.
