The error message looks a bit more fundamental than sendmail 
permissions. It appears that the mail() function invokes a shell to run 
the sendmail command, and it's unable to run the shell judging by the 
error message. So it's not getting anywhere near sendmail itself. Is the 
shell (/bin/sh perhaps?) accessible to your PHP scripts? Is your web 
server running chrooted perhaps?
