Gitlab pages sending emails via php

Hi Folks,

I have a static site page that has a contact form using a small php file to allow user to enter information and send an email to our support email address. I am using gitlab servers and the php code is able to run and gives me a status code 200, but I am not receiving any emails in my account. I feel the issue is related to email standards.

How would I get this to work using gitlab pages, on gitlab servers?
