Aws postfix mails going to spam

The eternal struggle with spam filters!

If you're experiencing issues with AWS Postfix emails going to spam, here are some potential causes and solutions to help you troubleshoot:

  1. DKIM (DomainKeys Identified Mail) configuration: Make sure you've set up DKIM correctly. You can use the AWS SES console to generate a DKIM key pair and update your DNS records.
  2. SPF (Sender Policy Framework) configuration: Ensure you've set up SPF correctly. You can use the AWS SES console to generate an SPF record and update your DNS records.
  3. DMARC (Domain-based Message Authentication, Reporting, and Conformance) configuration: If you're using DMARC, ensure you've set up the correct configuration. You can use the AWS SES console to generate a DMARC record and update your DNS records.
  4. Email content: Check the content of your emails for any spammy keywords or phrases. Avoid using all caps, excessive punctuation, or overly promotional language.
  5. Email headers: Verify that your email headers are correctly formatted and include the necessary information, such as the sender's email address, subject, and date.
  6. IP reputation: Check your IP reputation using tools like SenderScore or IP Reputation. If your IP has a poor reputation, it may be causing your emails to be flagged as spam.
  7. Blacklisting: Check if your IP or domain is listed on any blacklists, such as Spamhaus or SORBS. If you are listed, you'll need to take steps to resolve the issue and get delisted.
  8. Postfix configuration: Review your Postfix configuration to ensure it's set up correctly. Check the main.cf file for any settings that may be causing issues.
  9. AWS SES configuration: Verify that your AWS SES configuration is correct. Check the SES console for any errors or warnings.
  10. Email client configuration: If you're using an email client like Gmail or Outlook, check the configuration to ensure it's set up correctly.

To troubleshoot, you can try the following:

  1. Use a tool like Mail-Tester or SpamAssassin to analyze your email and identify potential issues.
  2. Check your email logs to see if there are any errors or warnings related to spam filtering.
  3. Use a spam filtering service like SpamAssassin or SpamFilter to analyze your email and provide recommendations for improvement.
  4. Reach out to your email provider or ISP for assistance with configuring your email settings or resolving any issues related to spam filtering.

Remember, preventing spam is an ongoing process that requires regular monitoring and maintenance. By following these tips and staying up-to-date with the latest best practices, you can help ensure that your AWS Postfix emails are delivered to the intended recipients' inboxes.
