Avoid getting mails flagged as spam

Step 1 and 2 are only relevant for AWS instances

  1. Assign Elastic (permanent) IP to your mail server instance.
  2. Create for it A record in corresponding DNS zone
  3. Use the AWS form to request AWS to create a valid PTR (reverse DNS) record for that IP
  4. Set up SPF, DKIM and DMARC records.
