Sendmail Return-Path

Hi Guys, I¹m using PHP¹s mail() function on several sites, but have difficulty sometimes with the mails being tagged as SPAM. I want to have the Return-Path set to the site admin, but can¹t see where to do this. I know that it can be done at server root level but I can¹t really do that as its a shared server. I do have my own php.ini file for my site, but can only see the following vars: mail function] ; For Win32 only. SMTP = localhost ; For Win32 only. sendmail_from = me@localhost.com ; For Unix only. You may supply arguments as well (default: "sendmail -t -i"). sendmail_path = /usr/sbin/sendmail -t -i I¹m working off a Linux box, so presumably I can¹t use the sendmail_from variable? I also tried to set the following variable in the headers for the mail: $headers .= "X-Return-path: ME <user@domain.com>\r\n"; Any help appreciated, Thanks Enda -- - + - + - + - + - + - + - + - + - + - + - + - + - Enda Nagle +353 86 168 0774 enda@category9.com www.category9.com - + - + - + - + - + - + - + - + - + - + - + - + -
