Email Class - Not able to set Return-Path header

[eluser]roguemonk[/eluser]
Got it!

Line 1540 (CI1.7.1) of the Email class (this is for sendmail... I believe it's similar for mail. Not sure about smtp):

$fp = @popen($this->mailpath . " -oi -f ".$this->clean_email($this->_headers['From'])." -t", 'w');

The -f flag sets the Return-Path.

Using this example switched the Return-Path for me:

$fp = @popen($this->mailpath . " -oi -f "."[email protected]"." -t", 'w');

In a real application, I would keep a variable, but make it point to _headers['Return-Path']. No angle brackets here.

Can someone confirm this for me.
