Server "from" e-mail address

[Matt]

The option you are referring to is from WHM > Exim Configuration:

Set the Sender: Header when the mail sender changes the sender (-f flag passed to sendmail)

Always set the "Sender:" header when the sender differs from the actual sender. Unchecking this will stop "On behalf of" data in Microsoft® Outlook, but may limit your ability to track abuse of the mail system.

My interpretation of the description of this setting, checking it off in your WHM will set the -f header for you when using the PHP mail() function so that it does not need to be set in php.ini. I do not think that it actually works though.

You can try enabling it in your WHM if it is not set already then retry your form processor and let us know how it goes.

This is a great topic - I've seen so many ways to form headers for sendmail, but I've had good luck with the following:

 if (strtoupper(substr(PHP_OS,0,3)=='WIN')) { 
  $eol="\r\n"; 
} elseif (strtoupper(substr(PHP_OS,0,3)=='MAC')) { 
  $eol="\r"; 
} else { 
  $eol="\n"; 
}  
$headers .= 'From: Mr. Person<person@domain.com>'.$eol; 
$headers .= 'Reply-To: Mr. Person<person@domain.com>'.$eol; 
$headers .= 'Return-Path: Mr. Person<person@domain.com>'.$eol;    // these two to set reply address 
$headers .= "Message-ID: <userid@".$_SERVER['SERVER_NAME'].">".$eol; 
$headers .= "X-Mailer: PHP v".phpversion().$eol;          // These two to help avoid spam-filters 
  

By your email above, I'll have to do some research to see if I need to add a "Sender:" header as well as the "From:". Maybe this has all changed since I last looked into it, but it is a good discussion.

I agree Charles, if you use [php] tags instead of [code] tags in your posts, the php will be easier to read. Do you want me to edit your post for you?

[charlesh]

Nah, should have done that in the first place. I'll post back with a "well-formed" header as well, working out the details now.

Thanks,

Well, Interesting findings - take a look at the following code -

   function send_mail($myname, $myemail, $contactname, $contactemail, $subject, $message) 
              {
              $headers .= "MIME-Version: 1.0\n";
              $headers .= "Content-type: text/html; charset=iso-8859-1\n";
              $headers .= "X-Mailer: PHP/" . phpversion()."\n";
              $headers .= "Reply-To:<".$myemail.">\n";
              $headers .= "From:".$myname."<".$myemail.">\n";

              
              return(mail("\"".$contactname."\" <".$contactemail.">", $subject, $message, $headers,"-finfo@harmonmediagroup.com"));
                } 
  

At first I just passed in "-finfo@harmonmediagroup.com" to the php mail function. Still didn't get anything different in the "Return-Path:" header - server generated. This proves that you can't override the EXIM configuration by passing a parameter.

Only after unchecking the "Set the Sender: Header when the mail sender changes the sender" option in WHM - MAIN>>Service Configuration>>Exim Configuration Editor under Mail, was I able to sucessfully pass on the additional parameter "-finfo@harmonmediagroup.com" and have it come up as such in the header's Return Path, which ultimately feeds into Oulook's "on behalf of" verbiage.

Not setting it in the mail function resorted to the default server username, but still did not generate the outlook "on behalf of" message in outlook.

Bottom line, I think I'll try it without the check box for a while - don't think it hurts anything.

[Matt]

Interesting. I still think there is another way around it in the script itself. I will have to try and find how we did this in the past.

Any reason you want to use charset=iso-8859-1 instead of UTF-8 ?

I guess I could change it now, I used it from another site I did (copied over) back in 2006 and we were having serious email problems with trying to get attachments through to end-users without being blacklisted. Somehow, I think I tried everything at the time to get it to pass. In the end, we just went to a "send you the link with a get statement" download type thingy. I could change it now to get with the times - thanks for pointing that out.
