Ubuntu 16 + Wordpress + WP Mail SMTP not send contact Form Emails

Hello I looked at several questions and answers but I still have doubts

I installed wordpress in ubuntu 16 I have my emails on hostgator Everything is working well

I installed WP Mail SMTP But the contact form does not send email

Do I need to install postfix? Or php email?



I don’t have an answer but I have the same problem. I tried installing Postfix and S-Nail, and while Postfix is installed, I can’t get S-Nail to send any messages because of a debug it doesn’t like. I am using’s VPS SSD, and I am also using Ubuntu 16.04 with WordPress.

Yes, you will need to install postfix (or any other MTA) to handle the actual process of sending emails. Take a look at the following tutorial which will help you accomplish that:

The last step, Forwarding System Mail, is not necessary and can be skipped if you do not want internal system mail to be forwarded to you.
