Advice needed for mail problem

[volcs0]

A new problem has cropped up with some of my php scripts. I have been using them to send email based on a form, both to the form owner as well as the submitter.

Starting a few days ago (after a server "upgrade"), any email that was supposed to go outside my domain started failing. The email is sent to the form owner fine (that is within the domain), but any email sent outside the domain gets bounced (I get a "unrouteable mail domain" error. My server admins have no idea why this started happening.

Here are the relavent parts of my script:

$email_header_conf = "From: [e-mail]\n"
. "Reply-To: [e-mail]\n";

mail("$Email", "Request - $Patient_Name", $body_conf_email, "$email_header_conf");

Do you think this is a PHP problem? Or a server/permissions/mail problem?

Thanks for the help.

This has nothing to do with PHP though, do you have a reverse PTR record?

Thank you for the quick reply. I don't have a PTR record (not know what one was, I just spent some time reading about them).

What sorts of questions/suggestions should I post to my system admins to help solve this problem?

Sorry to hijack the forum with a non-PHP question. I'm just getting desparate...

Thanks again for the help.

Tell your admin you need a REVERSE PTR RECORD for your domain name.

He should know what to do.

Thanks. I think I'm onto the problem. Any mail sent from my root account is bouncing. All my other accounts are fine. So, that explains why the PHP scripts are failing, anyways.

Thanks again for the help.
