Summary:

SELinux is preventing the sendmail from using potentially mislabeled files
/var/spool/clientmqueue (mqueue_spool_t).

Detailed Description:

SELinux has denied the sendmail access to potentially mislabeled files
/var/spool/clientmqueue. This means that SELinux will not allow httpd to use
these files. Many third party apps install html files in directories that
SELinux policy cannot predict. These directories have to be labeled with a file
context which httpd can access.

Allowing Access:

If you want to change the file context of /var/spool/clientmqueue so that the
httpd daemon can access it, you need to execute it using chcon -t
httpd_sys_content_t '/var/spool/clientmqueue'. You can look at the httpd_selinux
man page for additional information.
