## Description

Global SMTP is a utility plugin designed to easily configure SMTP for WordPress 
by adding a set of constants to your `wp-config.php` file.

When used with multisite, the configuration is applied network wide. This is often
handy to install as a “must use” plugin.

## Installation

#### Quick Setup

 1. Install the plugin, optionall as an mu plugin.
 2. Visit ‘Settings > Global SMTP Setup’ in your dashboard.
 3. Copy and paste the sample configuraiton to `wp-config.php` and update with your
    SMTP credentials.
 4. (optional) Add additional statements to complete the configuration for your smtp
    server.

#### Available Constants

**Required**
 GLOBAL_SMTP_HOST – The FQDN of the mail server (supplied by your SMTP
provider) GLOBAL_SMTP_USER – Username for accessing the mail server (most often 
your email address). GLOBAL_SMTP_PASSWORD – Password to authenticate your email 
account.

**Optional**
 GLOBAL_SMTP_FROM – Email address to use for outgoing mail. Uses WordPress
defaults when not set. Many hosts will force this to be the same as the username.
GLOBAL_SMTP_FROM_NAME – Name set in the From header for outgoing mail. Uses WordPress
defaults when not set. GLOBAL_SMTP_PORT – Port number for SMTP connection. Assumed
as 587 (for tls). GLOBAL_SMTP_SECURE – Encryption type. Assumed to be ‘tls’. Can
be ‘ssl’, ‘tls’, or ‘none’. GLOBAL_SMTP_AUTH_TYPE – Authentication type. Defaults
to ‘LOGIN’, can also be ‘PLAIN’ or ‘NTLM’.

    ```
    GLOBAL_SMTP_RETURN_PATH - Address to send bounced emails.

    GLOBAL_SMTP_REPLYTO_FROM - Email address shown in recipients mail client when clicking "Reply"

    GLOBAL_SMTP_DISABLE - Set to true to prevent this plugin from hooking into `wp_mail`. This is useful for environment specific configurations.
    ```

#### Troubleshooting

For troubleshooting, we recommend that you install the check email plugin:
 https://
wordpress.org/plugins/check-email/

If you add this statement to `wp-config.php` you will see debug output when sending
a test email via that plugin.

    ```
    define('GLOBAL_SMTP_DEBUG',true);
    ```

## FAQ

  What does this plugin do?

It allows you to configure WordPress to send email via an SMTP account. You can 
use gmail for example.

  How does this plugin work?

Global SMTP hooks into the existing PHP Mailer class in WordPress and switches it
to use SMTP mode. It then provides the mailer class with SMTP credentials using 
values that you place in `wp-config.php`

 [ze3kr](https://profiles.wordpress.org/ze3kr/) September 3, 2016

This is the only SMTP plugin I found that works excellent with Multisite installed
WordPress. And supports TLS, SSL, and don’t use database and very fast!
