note 10273 added to mail

If your PHP4 mail command (sendmail) or the running of any external program doesn't appear to work in a chroot environment, it might be because the sh shell is not available in the restricted environment. The sh shell is required as without it, sendmail and the running of all external programs would just be ignored silently. Regards, Kwong Li London, UK http://www.php.net/manual/function.mail.php
