README

GtSmtp is a WordPress plugin for sending emails via SMTP instead of the default PHPMailer.

Requirements

• Composer version 2+ https://getcomposer.org/

Installation

Installing this plugin assumes you are managing plugins for a WordPress site with composer or wp-packagist. It is currently not part of the WordPress plugin repository so it can't be installed with wp-packagist.

Add the following configuration to your composer.json. If you are managing plugins with wp-packagist, this configuration may already be present.

    "extra": {
        "installer-paths": {
            "plugins/{$name}/": ["type:wordpress-plugin"]
        }
    }

Install with composer

composer require grofftech/gt-smtp

Activate the plugin from the WordPress administration area. Once the plugin is successfully activated the smtp-config.php file will be automatically created in wp-content/gt-smtp-config. Update this file with the relevant SMTP server settings.

From the WordPress administration area, click on the GT SMTP from the menu. Verify the settings added in smtp-config.php display. Note that the password will not display here.

Testing

From the WordPress administration area, navigate to GT SMTP > Email Test. Enter in a valid email address in the Email To field and click Send Email.
