WP SMTP Config

Description

This plugin configures WordPress and WordPress MU to use a SMTP server when sending emails instead of the default PHP mail() function.

You will configure your SMTP settings in your wp-config.php file instead of the settings page.
The advantage is that no admin of your blog can read the settings.
And you only have to place your settings once in cases of a WordPress MU installation.

A sample configuration:

/**
 * WordPress SMTP server
 */
define('WP_SMTP_HOST',       'mail.example.com');
define('WP_SMTP_PORT',       25);                                // obligatory - default: 25
define('WP_SMTP_ENCRYPTION', 'tls');                             // obligatory ('tls' or 'ssl') - default: no encryption
define('WP_SMTP_USER',       'username');                        // obligatory - default: no user
define('WP_SMTP_PASSWORD',   'password');                        // obligatory - default: no password
define('WP_SMTP_FROM',       'John Doe <john.doe@example.com>'); // obligatory - default: no custom from address
define('WP_SMTP_REPLYTO',    'Jane Doe <jane.doe@example.com>'); // obligatory - default: no custom reply to address

Installation

  1. Upload wp-smtp-config.php to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Place the SMTP details (see Description) in your wp-config.php file above the line /* That’s all, stop editing! Happy blogging. */
  4. Test your settings (Settings -> SMTP)

FAQ

Where is my SMTP settings page?

The configuration of the SMTP server credentials will be placed in your wp-config.php file only.
You can test your configuration in Settings -> SMTP Test.
If you are running a MU installation you will find this settings page for SMTP Test in your network settings.

The plugin is no longer sending emails on any of my sites. The SMTP Test” link that is supposed to appear in the Settings menu after installation does not appear. If you visit this test page by directly entering the URL in the location bar, the page just says Sorry, you are not allowed to access this page.” The plugin has not been updated for Wordpress 5.x so I guess it isn’t working because it is no longer compatible with latest Wordpress versions.

We want to route all email traffic on multiple mulitsite networks through an SMTP server…rather than configuring many times, throwing this into the wp-config and network activating the plugin works great.
