PHP's mail() function uses popen() instead of execve() to call the sendmail executable. This was probably done because it saved the parameter parsing, but it makes it impossible to use PHP's mail() function inside of a chroot() jail unless /bin/sh is copied inside the chroot()-ed environement.

As more and more Apache installs get chroot()-ed, it would be nice to rewrite the code to properly use execve().

Proper solution is to not use external executables to handle mail.
Code s in there, see #9308
