Email Sending Checklist


Things most mail servers demand/require to ensure delivery:

  • rDNS of sender IP matches sender domain and/or SPF record
  • SPF record allows mail server to send mail for domain – see: www
  • Setup DKIM/DomainKeys on DNS server + email server – see: our guide for DKIM and Postfix


Send emails to either (or both) of these emails to test SFP records & other things

  • (the email will bounce, look for test ="pass" in the response error)
