It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://ps.w.org/g-smtp/assets/icon-128x128.gif?rev=2724554) # G-SMTP By [The Generation](https://profiles.wordpress.org/thegeneration/) [Download](https://downloads.wordpress.org/plugin/g-smtp.1.1.5.zip) * [Details](https://tzm.wordpress.org/plugins/g-smtp/#description) * [Reviews](https://tzm.wordpress.org/plugins/g-smtp/#reviews) * [Installation](https://tzm.wordpress.org/plugins/g-smtp/#installation) * [Development](https://tzm.wordpress.org/plugins/g-smtp/#developers) [Support](https://wordpress.org/support/plugin/g-smtp/) ## Description G-SMTP is a next Generation SMTP-plugin built to last. This is a plugin that helps you send your e-mails via SMTP, and only that. All the SMTP-details are setup as constants via wp-config.php, making it stable and does not have to rely on the database for the e-mails to be delivered. ## Screenshots * [[ * Overview of settings page where you can verify the connection * [[ * Configuration page where you can generate constants to put in your wp-config. php ## Installation 1. Install the plugin either through your web browser in the WordPress admin panel or manually through SFTP/FTP. 2. Activate the plugin 3. Setup the constants in `wp-config.php` as described below or use the configuration page at **Settings > G-SMTP > Config** to generate them 4. Test the settings by going to **Settings > G-SMTP** and sending a test e-mail #### 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 ); ``` ## Reviews There are no reviews for this plugin. ## Contributors & Developers “G-SMTP” is open source software.
