PHP mail() not working

Hosting Support

Hello,

I am working on a support system for one of my websites.

I am noticing that PHP’s mail() function does not work when attempting to send an email. Can this be fixed? Thanks.

PHP mail() works fine, just make sure you set a proper From: header with an e-mail address you’re authorized to send from and send it to a different address.

For some reason it doesn’t want to send.

Am I doing it right?

(Email is already defined by the way. Also may this be an issue with CloudFlare?)
