php mail not working as I want it to

I am trying to add a new php module within the ZC admin folder but emailing not working as expected.

I tried this which works outside of ZC
mail($ToEmail,$subject . ' php mail',$tempTemplate,$headers) ;
and there are no errors but nothing happens when running within ZC with the normal
require('includes/application_top.php');
and
require('includes/configure.php');

It works outside of ZC without the above requires.

I even tried using zen_mail but does do what I need it to do.
.
$aaatex_html_msg['EMAIL_FROM_ADDRESS'] = $fromEmail;
.
zen_mail( '', $ToEmail, $subject , $tempTemplate, "AaaTeX Customer Service", "[email protected]", $aaatex_html_msg,'renewals');

It sends the email but there are 2 issues:

1. It doesn't use the from email above but uses the store email address which I do not want.
2. It doesn't seem to support Bcc.

So how can I get it to send emails with the from address and Bcc? I think that php mail would be preferable but it does nothing.

The zen_mail function's standard processing (except for contact_us and order-confirmation emails) has the reply-to field set to the store's email address. You can override that behavior in the zen_mail call, though:

zen_mail ( '', $ToEmail, $subject , $tempTemplate, STORE_NAME, EMAIL_FROM, $aaatex_html_msg,'renewals', '', "AaaTeX Customer Service", "[email protected]");

While Zen Cart doesn't support bcc: mails out-of-the-box, you could write an observer-class script to receive notifications on NOTIFY_EMAIL_READY_TO_SEND (as its name implies, the email's just ready to send). You receive a copy of the phpMailer object ($mail) as the second notification parameter, allowing you to add the BCC addresses via the phpMailer's *AddBCC *function.
