selinux and feedback from web

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!
