## Description

 * **Just SMTP** allows you to set up mail delivery via SMTP.
 * Input your server, user, password data and you’re good to go.
 * This plugin doesn’t add a top-level menu item, has no ads, nags or other clutter.
 * Just SMTP does just that: SMTP.

#### What this plugin does not provide

 * Mail delivery without SMTP authorization (i.e. without username and password).
   You shouldn’t want to anyway.
 * Mail delivery without TLS or SSL encryption. That’s just not a thing anymore.
 * Mail delivery via Exchange, Google Workspace or similar services that require
   more complex authorization.
 * Error logging or any sophisticated debugging. It does have a mail tester though.

## Installation

 1. Upload the plugin files to the `/wp-content/plugins/just-smtp` directory, or install
    the plugin through the WordPress plugins screen directly
 2. Activate the plugin through the ‘Plugins’ screen in WordPress
 3. Configure your settings using the Settings->SMTP screen

## FAQ

### How can I debug sending errors?

Use the Tester to send a test mail. The resulting PHPMailer log of that test mail
will be output for you to review.

### How can I protect the password?

If a constant ‘JUST_SMTP_ENCRYPTION_KEY’ is set, the password will be stored encrypted.

You can define this constant in your wp-config.php file like so (switch out the 
random string with your own): define( ‘JUST_SMTP_ENCRYPTION_KEY’, ‘randomstring’);
Make sure to re-save the password after adding this constant. If the constant value
gets changed, the passwords needs to be saved again.
