php mail function only working on local server and not on remote server

just as the title I created a simple form in HTML

you can see it at http://thee-l.comuv.com/send.php this sends an email to me with the subject and body text specified I run this on localhost from Apache and I get in my inbox in less than a minute but I then upload it to the remote server the site and it does not email me at all

I have a gmail address so to make it easy I made an outgoing smtp server with smtp2go this was my first php-sent email, I was really happy and right away put it on the remote server and here we are

I am using 000webhost
