mail() issues "Return-Path: "

[rrsub]

On a Win32 platform;

In my php.ini, I have set 'sendmail_from=me@domain.com;'

In my headers I have a proper 'Return-Path:' and 'From:' with the "\r\n" and other required header information that gets passed correctly.

I'm using mail($to,$subject,$message,$headers);

My problem is that the 'Return-Path:' in the client who recieves the email is set to what the php.ini is set to and not what the header is set to.

If I comment out the line in the php.ini, I get an error that says that I don't have a Return-Path: or a From: available in my header.

My Return path is 'Return-Path: me@domain.com\r\n'
My From is 'From: My Name<me@domain.com>\r\n'

The "From" is fine but what happens is that email address that is the 'To: ' has an autoresponder and automatically send a message to 'sendmail_from' and not 'Return-Path:'

What about sending a reply-to header? Have you tried that?

 

[rrsub]

Yup.

$headers = "".
"Content-Type: text/html \r\n".
"Date: ".date("r")."\r\n".
"Return-Path: ".$return_path."\r\n".
"From: ".$hdr_from."\r\n".
"Sender: ".$hdr_from."\r\n".
"Reply-to: ".$hdr_from."\r\n".
"Organization: domain.net\r\n".
"X-Sender: ".$hdr_from."\r\n".
"X-Priority: 3 \r\n".
"X-Mailer: Domain-Mailer \r\n";

$hdr_from is chosen from the site owner.
$return_path is either the site owner or the form users email address.

I know the return path is supposed to be where the mail gets bounced to if the 'To: ' is invalid but the autoresponder sends the message to the 'Return-Path:'

Figured it out.

Not many responses on this question. Do you guys use the mail() function?

Anyway, here's my solution;

ini_set("sendmail_from",$return_path);

$headers = "".
"Content-Type: text/html \r\n".
"Date: ".date("r")."\r\n".
#"Return-Path: <".$return_path.">\r\n". // Might as well remove this
"From: ".$hdr_from."\r\n".
"Sender: ".$hdr_from."\r\n".
"Reply-to: ".$hdr_from."\r\n".
"Organization: domain.net\r\n".
"X-Sender: ".$hdr_from."\r\n".
"X-Priority: 3 \r\n".
"X-Mailer: Domain-Mailer \r\n";

Do you guys user the mail() function?

I do, but generally only indirectly. If I have do send complex emails, I generally use the PHPMailer class.


Also, mail() on Win32 behaves differently from mail() on unix-like OSes. And different MTAs on unix-like OSes behave differently from one another in how they interact with PHP.
