How Do I Connect PHP Email Script to Postfix?

I have a VPS where I’ve installed my site files, including the PHP email script that uses the php mail() function inside of the following directory (how my site directory/path is set up):


And when I installed Postfix, I’ve configured it to send email through Amazon SES. Postfix has been installed inside of the following directory:


The problem that I’m having is that it will send email from the command line when testing that Postfix has properly installed along with using the Amazon SES SMTP, BUT my php email script DOESN’T connect from my websites folder directory to Postfix.

How do I connect my php email script to Postfix? Do I need to change directories?

Here is the php mail() function script that I’m using below:

$to = "";
$subject = "Another Test!";
$txt = "Hello world!";
$headers = "From:" . "\r\n" .

if you created the script under Windows or OSX, edit further it under Unix:

sed -i -e 's/\r$//' email_script.php

Hello, @AaronEsteban1

The code itself looks good, have you checked the PHP error_log for further troubleshooting as well? You can find the exact location of the error_Log by checking the php.ini file. If there are any errors they should be logged in the log.

Let me know how this goes.
