Spam mail black list

A spam mail blacklist is a list of email addresses or domains that are known to send spam or unsolicited commercial emails. Here are some popular spam mail blacklists:

  1. Spamhaus: One of the most widely used and respected blacklists, Spamhaus has a comprehensive list of IP addresses and domains known to send spam.
  2. Sender Policy Framework (SPF): SPF is not a traditional blacklist, but rather a protocol that helps prevent spam by verifying the authenticity of email senders.
  3. DomainKeys Identified Mail (DKIM): DKIM is another protocol that helps prevent spam by verifying the authenticity of email senders.
  4. Open Relay Blackhole List (ORBL): ORBL is a list of IP addresses that are known to be open relays, which can be used by spammers to send spam.
  5. Real-time Blackhole List (RBL): RBL is a list of IP addresses that are known to be involved in sending spam.
  6. Surbl: Surbl is a list of IP addresses and domains known to send spam.
  7. SpamRBL: SpamRBL is a list of IP addresses and domains known to send spam.
  8. SORBS: SORBS (Spam and Open Relay Blocking System) is a list of IP addresses and domains known to send spam.
  9. CBL: CBL (Combating Spam and Abuse List) is a list of IP addresses and domains known to send spam.
  10. DNSWL: DNSWL (Domain Name System White List) is a list of IP addresses and domains known to be legitimate and not involved in sending spam.

These blacklists are used by email providers, ISPs, and organizations to filter out spam emails and prevent them from reaching their users' inboxes. If your email address or domain is listed on one of these blacklists, it may affect your ability to send emails to other users.

To avoid being listed on a spam mail blacklist, it's essential to follow best practices for email marketing and avoid sending unsolicited or spammy emails.
