Description marco 2010-05-03 18:26:45 UTC
Summary:

SELinux is preventing /usr/sbin/sendmail.postfix access to a leaked tcp_socket
file descriptor.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by the sendmail command. It looks like this is
either a leaked descriptor or sendmail output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the tcp_socket. You should generate a bugzilla on selinux-policy, and it will
get routed to the appropriate package. You can safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)
