cPanel Server DNS Issues Affecting Outbound Email

[dr00t]

I recently noticed that several PHP scripts on my sites that send to external email addresses when submitted, are bouncing back mail to the "default account email address" for that account.

I checked, and the email destination is fine - so I believe the DNS affecting outbound email FROM my server is screwed up. Anyone have any idea where I go to confirm / check this setting? I cannot figure out how to even see what DNS records are being referenced when mail is being sent from my server.

Thank you in advance!

Hello

What method is the script using to send out email? Is it using SMTP authentication or the Mail function with PHP?

Thank you.

Thank you.

The Mail function with PHP.

The default behavior when sending email through PHP is to use the cPanel username and hostname of the server to construct the envelope-sender address. If you can configure the mailer to use SMTP and authenticate with SMTP AUTH, this will set the correct "Return-Path" in the headers.

Thank you.

I guess my next questions is... how do I configure the mailer to use SMTP and authenticate with SMTP AUTH

It depends on the specific script you are using. Check with a developer or support team for that script to see if you can enable it directly, or if any custom modifications are required.

Thank you.
