Form Mail Sending Locally (Not using AWS Account)

Hello,

I have a form mail set up with an AWS account. The SMTP settings are configured correctly in the action file, and the form functions. However, upon checking the form, it seems to be sending it locally rather than using the AWS account.

We have a several symptoms:

1. The email fails to show in some inboxes. Upon testing, these results came back for deliverability, 6.7/10 (https://www.mail-tester.com/test-s6j7zv84v&reloaded=1)
2. The records for the AWS account show no emails being sent with the AWS account

We need to fix this issue so that the template sends email notifications from the AWS account.

FORM ACTION FILE SMTP CREDENTIALS: "contact-form-test.php"

$mail->Host = 'smtp.zeptomail.com'; // Set the SMTP server to send through
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'emailappsmtp.2b64ab45'; // SMTP username
$mail->Password = 'suhpL0W8nCVr'; // SMTP password
$mail->SMTPSecure = 'TLS'; // Enable TLS encryption
$mail->Port = 587;

Here is the form code:
