Hi, My system information -- os: RedHat FC3 linux, kernel-2.6.10-1.741_FC3, selinux enforced, iptables enabled selinux: selinux-policy-targeted-1.17.30-2.73 (the most update one) iptables: iptables-1.2.11-3.1.FC3 web: httpd-2.0.52-3.1 sendmail: sendmail-8.13.1-2 php: php-4.3.10-3.2 SELINUXTYPE targeted I have a testing feedback php code for my web site using mail($toaddress, $subject, $mailcontent, $fromaddress); If selinux is disabled, the code works well. The user ($toaddress) receives the content ($mailcontent), etc. However, if selinux is enforced, the user does not receive it and the system log shows: Jan 28 14:19:46 pippo kernel: audit(1106943586.048:0): avc: denied { read } for pid=6801 exe=/usr/sbin/sendmail.sendmail name=clientmqueue dev=hda3 ino=470506 scontext=user_u:system_r:httpd_sys_script_t tcontext=system_u:object_r:mqueue_spool_t tclass=dir Should I do something to make it working with selinux enforced? Thanks! Hongwei
