SAR Friendly SMTP vs NotifSMS – SMS Notifications OTP & 2FA for WordPress & WooCommerce

There are A LOT of SMTP plugins for WordPress, some uses third-party libraries with no too much luck, others looks like the same plugin (almost identical source code) but with different name… Most of them overwrites from address and from name fields ALWAYS, breaking functionality of some other plugins that send emails using wp_mail() function. So the history repeats again, I can’t find one simple plugin that fits my needs, so I created one for myself and share it with you in the hope that you’ll find it useful. If you’re happy with the plugin please don’t forget to give it a good rating, it will motivate me to keep sharing and improving this plugin (and others). IMPORTANT: Support requests must be created using the Issues tab at the Github repository Features KISS principle. No third-party libraries for SMTP, uses WordPress core. Respect fields modified by other plugins (e.g. Gravity Forms). Option to enable debug mode (logs communication between WordPress and your SMTP server in PHP’s error_log file, check FAQ for more details). Uses WordPress settings API for settings page, making it secure by default. Custom capability for settings access, so you can allow non administrator users to access to the settings page if you need it using User Role Editor (or any other similar plugin). Send Email Test page. Allowing you to test if WordPress is able to send emails using the SMTP server details provided. Constants available to override settings using wp-config.php (useful to set same settings network-wide on a multi-site installation). Requirements PHP 7.0 or higher. WordPress 4.9 or higher. SMTP server 🙂 It may work with older versions of PHP and WordPress (and it does in fact at the time of writing this), but I don’t support anything older than the versions mentioned above. Usage Just install in your WordPress like any other plugin, activate it and fill settings using your SMTP server details. If you’re not sure about what you need to put in each field, ask to your SMTP server support.
