[FIXED] How to use a custom SMTP settings in my WordPress site

Issue

I need to use custom SMTP settings for my WordPress site to send email through my email servers such as Mailgun or SendGrid.

Solution

Place this in your theme function.php or your own plugin.

add_action( 'phpmailer_init', 'custom_phpmailer_init' );
function custom_phpmailer_init( $phpmailer ) {

    $phpmailer->isSMTP();
    $phpmailer->Host = 'smtp.mailgun.com';
    $phpmailer->Port = 465;
    $phpmailer->Username = 'user_name';
    $phpmailer->Password =  '********';
    $phpmailer->SMTPAuth = true;
    $phpmailer->SMTPSecure = 'ssl';
    $phpmailer->From       = 'FromName@example.com';
    $phpmailer->FromName   = 'FromName';

}
