All our servers have the capability to send email from your WordPress applications. By default, WordPress uses the PHP mail() function to do this, which in turn uses the native application on the server to send the actual email messages -- usually postfix.
In some cases it may be preferable to instead send email from your WordPress application via an external SMTP server, such as Google Apps for Work or Office365.
This is easy enough to do, thanks to a free WordPress plugin called WP Mail SMTP.
With WP Mail SMTP you can easily configure your WordPress site to send email via any external SMTP server. It also supports sending email with SSL or TLS encryption for added security.
To set this up, you will need:
- An email address / username and password for an account on the SMTP server
- The SMTP server's URL, such as
smtp.gmail.com - The SMTP server's port, such as
465
