Description Tobias Mueller 2010-08-22 13:07:44 UTC

SELinux is preventing /usr/sbin/ssmtp "getattr" access on /etc/aliases.

Detailed Description:

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

SELinux denied access requested by sendmail. It is not expected that this access
is required by sendmail and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

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