Josh, thanks for using the policy without unconfined module. The note: You don't need to remove uncofined module, you can only disable this module using "semodule -d". So you could execute now # semodule -i /usr/share/selinux/devel/targeted/unconfined.pp.bz2 # semodule -d unconfined.pp type=AVC msg=audit(1320499351.616:172489): avc: denied { read } for
pid=12711 comm="mail" name="mail" dev=dm-0 ino=1836031
scontext=staff_u:sysadm_r:user_mail_t:s0-s0:c0.c1023
tcontext=system_u:object_r:mail_spool_t:s0 tclass=lnk_file
is allowed in Fedora. Will backport.
The question is /root/.mailrc. It looks like we could treat it with mail_home_t. Something like we have for .dead_letter

Thanks, Josh The bug should be fixed now, but we aren't able to reproduce the bug even with older selinux-policy. Josh, could you please install the current selinux-policy and confirm the bug is really fixed. (the newest version is 3.7.19-143 and can be downloaded from here: http://people.redhat.com/dwalsh/SELinux/RHEL6/noarch/ ) Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
