'From' email header reflects host email and I can't change it

Try making a simple PHP script that just calls mail(), http://us.php.net/manual/en/function.mail.php. This will show if it is a problem with Drupal or the hosting company. It is possible that the hosting company's mail server is overwriting the from address. In that case, you need to talk to the hosting company.

My client experienced the same problem with Drupal 5.9. It turned out it was the hosting provider (Hostmonster) overwriting the "from" header. My client needed to add the e-mail address to his Hostmonster account, using the cpanel. Once he did that, Hostmonster recognized the "from" address as legitimate and no longer overwrote it.

well I suppose that if you changed in common.inc

$default_from = variable_get('site_mail', ini_get('sendmail_from'));

to

$default_from = variable_get(ini_get('sendmail_from')); 

everything would be ok :D

mcannell:
Could you maybe provide us a test mail including the complete headers as received in the mailclient? That would be helpful. I'm working on #165938: Pass Return-Path via the mail -f parameter and #346545: Add a 'site_mail_internal' address variable, and this might be connected.

see also the related issue #131737: Ensure that the Return-Path is set when sending mail on both Windows and non-Windows systems.

I have hostmonster also and I am encountering this same problem. Does this hack mentioned work?

$default_from = variable_get('site_mail', ini_get('sendmail_from'));

to

$default_from = variable_get(ini_get('sendmail_from'));

****FYI**** THIS DOES NOT WORK!!!!!

To solve the "on behalf of" problem, set a "Sender" value in the headers.

Thank you but could you elaborate?

After hours of googling and trying different things I finally have a solution.
It turns out that its probably not a problem with drupal at all but a problem with your exim configuration.
Try editing exim.conf (probably located at /etc/exim.conf).
Change "local_from_check" from true to false.
Then go ahead and send out a mail with drupal, and see if it works, it did for me.
The reason this works is because Exim will modify the "Sender:" header if your user account is not a "trusted" one.
(Please note: even if you're sending -f to the php mail() function, it will be ignored and the Sender: header will still be appended by exim so the return path module - http://drupal.org/project/returnpath will be little help in this regard ).
Another solution is to modify the trusted_users option in the exim configuration - and add the user that php runs as there.
Please confirm if this works for you or not.
Hope this helps!

Interesting. I don't have anything like this file in my account. I am wondering if it is because we don't host our email on the same host as our website.

Closing since this is not a Drupal issue. Drupal doesn't control email server configuration.

#12 - mparas.

Your suggestion worked for me - thanks!

$headers = array(
    'MIME-Version' => '1.0',
    'Content-Type' => 'text/html; charset=UTF-8; format=flowed',
    'Content-Transfer-Encoding' => '8Bit',
    'X-Mailer' => 'Drupal',
    'Sender' => "email@address.com"
  );
