Create a properly formatted SPF DNS record to authorize mail servers for your domain.

About SPF Records

  • • SPF authorizes which mail servers can send email on behalf of your domain
  • • SPF records are published as DNS TXT records at your root domain
  • • Keep DNS lookups under 10 to avoid validation failures
  • • Use -all (hard fail) for maximum protection
