Send form mail using an SMTP relay server
To send form mail, we recommend using applications or scripts that use the PHP mail() function (for example, Contact Form 7 for WordPress). But if your contact form requires Simple Mail Transfer Protocol (SMTP), you can use the relay settings below.
Note: While we're happy to provide information on form mail, we do not directly support the functions and reliability of third-party plugins, scripts, or mail providers. For more information, view the Statement of Support.
| Setting | What to use |
|---|---|
| Port | 25 |
| SMTP Authentication | False, None, or turn off |
| SSL or Secure Connection | False, None, or turn off |
| Server or Host | relay-hosting.secureserver.net1 |
| Add an SPF record2 | v=spf1 include:secureserver.net -all |
- If you use a PHP script and the
mail()function, you do not need to specify a relay server. - If you use an SMTP relay server, you must add the appropriate sender policy framework (SPF) record. Without this, your form emails can fail authentication and not be received.
