This plugin is relying just on your <code>wp-config.php</code> file. It uses smtp connection details you will set up there to configure WordPress to relay all outgoing emails through that email server.
<h4>Background</h4>
There are plenty of similar type of plugins out there. Most of them are not focused on relaying emails to an SMTP server, but rather supporting specific mail services.
But the main incentive for this was the fact that the <a href="https://hub.docker.com/_/wordpress" rel="nofollow ugc">official WordPress docker image</a> doesn’t have support for sending out emails (eg. “forgot password”).

WP SMTP Mailer – SMTP7

Takes 2 minutes (at most) to set up and works perfectly.

Quick and handy


It's a no-nonsense way to set up SMTP. I use Brevo for the relay server. They have a nice free tier. Combined with Brevos's easy-to-find API key, it's no sweat to have emails sent from your domain. For example, From address: your.name@yourdomain.com From name: Head Editor 



Getting an email sent to you@yourdomain.com is a whole other can of worms. But it's nice that this plugin doesn't have that. It keeps the settings simple.
