Detailed Description SELinux has denied /usr/sbin/sendmail.postfix access to potentially mislabeled file(s) (/tmp/.apc.541B8K (deleted)). This means that SELinux will not allow /usr/sbin/sendmail.postfix to use these files. It is common for users to edit files in their home directory or tmp directories and then move (mv) them to system directories. The problem is that the files end up with the wrong file context which confined applications are not allowed to access. Allowing Access If you want /usr/sbin/sendmail.postfix to access this files, you need to relabel them using restorecon -v /tmp/.apc.541B8K (deleted). You might want to relabel the entire directory using restorecon -R -v /tmp.

Actual Results: Expected Results: Additional info:
This is a leaked file descriptor from PHP. Which your PHP/apache execs the sendmail program it is not closing all of its file descriptors so the kernel checks to see if system_mail has access, and then closes the file descriptor. You can safely ignore this, but upstream mod_php should be informed that they have a leaked file descriptor
I have reported the problem to the php team
