Configure a SMTP server to send email from your WordPress site. Configure the wp_mail() function to use SMTP instead of the PHP mail() function.
== Description ==
[SMTP Mailer](https://wphowto.net/smtp-mailer-plugin-for-wordpress-1482) plugin allows you to configure a mail server which handles all outgoing email from your website. It takes control of the wp_mail function and use SMTP instead.

* **SMTP Authentication**: Whether to use SMTP authentication when sending an email (True/False). If you choose to authenticate you will also need to provide your username and password.
* **SMTP Username**: The username to connect to your SMTP server.
* **SMTP Password**: The password to connect to your SMTP server.
* **Type of Encryption**: The encryption to be used when sending an email (TLS/SSL/No Encryption. TLS is recommended).
* **SMTP Port**: The port to be used when sending an email (587/465/25). If you choose TLS the port should be set to 587. For SSL use port 465 instead.
* **From Email Address**: The email address to be used as the From Address when sending an email.
* **From Name**: The name to be used as the From Name when sending an email.
=== SMTP Mailer Test Email ===
