Blacklist mail test

A "blacklist" in the context of email is a list of email addresses or domains that are known to send spam or other unwanted emails. Here's a test to check if your email address is blacklisted:

Step 1: Check the most popular blacklists

  1. Spamhaus: Go to www.spamhaus.org and enter your email address in the "Check IP" or "Check Domain" field. If your IP address or domain is listed, it may be blacklisted.
  2. Sender Score: Go to www.sender-score.com and enter your email address. If your score is low, it may indicate that your IP address or domain is blacklisted.
  3. Open Relay Test: Go to www.openrelaytest.com and enter your email address. If your IP address is listed, it may be an open relay, which can lead to blacklisting.

Step 2: Check your email provider's blacklists

  1. Gmail: Go to www.google.com/postmastercentral and sign in with your Gmail account. Check the "Blacklist" section to see if your IP address or domain is listed.
  2. Yahoo: Go to postmaster.yahoo.com and sign in with your Yahoo account. Check the "Blacklist" section to see if your IP address or domain is listed.
  3. Microsoft: Go to www.barracudacentral.org/rblcheck and enter your email address. If your IP address or domain is listed, it may be blacklisted.

Step 3: Check your email client's blacklists

  1. Thunderbird: Go to "Tools" > "Account Settings" > "Server Settings" and check the "Blacklist" section.
  2. Outlook: Go to "File" > "Options" > "Trust Center" > "Trust Center Settings" and check the "Blacklist" section.

What to do if you're blacklisted

If you're blacklisted, it's essential to take immediate action to resolve the issue. Here are some steps to help you get off the blacklist:

  1. Check your email server configuration: Ensure that your email server is properly configured and not open to spam.
  2. Verify your domain ownership: Make sure you own the domain and have control over the DNS settings.
  3. Remove any spam traps: If you have any spam traps in your email list, remove them to prevent further blacklisting.
  4. Implement email authentication: Set up email authentication protocols like SPF, DKIM, and DMARC to prevent spam and phishing attacks.
  5. Contact the blacklist provider: Reach out to the blacklist provider and provide them with the necessary information to resolve the issue.

Remember, being blacklisted can significantly impact your email deliverability and reputation. It's crucial to take proactive measures to prevent blacklisting and maintain a good email reputation.
