How Simple SMTP works
Show full descriptionShow less
Adds a simple, no-fuss SMTP settings to your WordPress installation that lets you define custom settings, which is especially useful for hosts with no control over the php mail functionality.
If logging is enabled, a new segment in the settings panel will show up with a 30-day overview of recent emails, and will automatically prune older logs. Please see the FAQ if you want a more permanent solution.
For more information, please see the project wiki on GitHub.
Environment and constant overriding (optional) This plugin will prefer environmental and constant-stored values over the plugin-saved equivalent settings, making it easier to use this plugin via deployment.
These can be either stored in your systems env setup, or in wp-config.php as define( 'SEE_BELOW', 'your_value_here' );.
