Constants

These are the base constants needed to make the plugin work:

define( 'G_SMTP_ENABLED', true );
define( 'G_SMTP_HOST', 'my-smtp-host.com' );
define( 'G_SMTP_PORT', 25 );

Below, you will find information regarding the different constants available:

Activated/deactivated (mandatory)
This sets if the SMTP-connection should be enabled or not. It can be used for debugging-purposes and should be left as true generally.

define( 'G_SMTP_ENABLED', true );

Host (mandatory)
Here you enter which domain/IP-address where the SMTP-service is hosted.

define( 'G_SMTP_HOST', 'my-smtp-host.com' );

Port (mandatory)
Here you enter what port the SMTP-service is hosted on. Generally the ports 25 (non encrypted), 465 (SSL) and 587 (TLS) are used.

define( 'G_SMTP_PORT', 25 );

Encryption (optional)
This defines if an encrypted connection should be used when connecting to the SMTP-service. Normally you should enter ssl if the port is 465, tls if the port is 587 and leave it empty if the port is 25.

// TLS connections (port 587)
define( 'G_SMTP_ENCRYPTION', 'tls' );

// SSL connections (port 465)
define( 'G_SMTP_ENCRYPTION', 'ssl' );

Username and password (optional)
If the SMTP-service requires authentication then you must enter username and password.

define( 'G_SMTP_USER', 'username' );
define( 'G_SMTP_PASSWORD', 'password123' );

Sender, name and e-mail (optional)
If you want to override the sender name and e-mail address you can enter these settings.

define( 'G_SMTP_FROM_NAME', 'Sender name' );
define( 'G_SMTP_FROM_ADDRESS', 'sender@sender.com' );

This overrides the default settings, if plugins have other settings then those will be used.

If you want name and e-mail address to always be overriden then you can use this setting:

define( 'G_SMTP_FORCE_FROM', true );
