However using PHP Mail... would send the bounce back to www@host.com, as the PHP Mail implementation doesn't set the -f argument (provided that the mta didnt ignore the Errors-To...). This is what originally led me to investigate this why this was happening. Im guessing that the developers didnt set the -f argument in the Mail implementation as it may not be used in all mta's? although ive only worked with sendmail & qmail, but it looks like most mta's support this argument (ie sendmail, qmail, exim, postfix), wouldnt know about windows systems however.... So does the Errors-To overide the Return-Path??? not on my box.....
