Thank God for this plugin

I spent hours trying to hack my way around the wp_mail to get WordPress to send an email. I’m running WordPress as a subdir in a project hosted on a Google Cloud instance which blocks the standard SMTP ports so the wp_mail and mail methods don’t work. I used Swiftmailer somewhere else in the instance and it’s able to send emails so I was trying to hack the wp_mail function to use Swiftmailer but that would’ve taken me hours. I installed this plugin and had WordPress send an email in literally seconds. THANK YOU
