--- Comment #2 from Steve Tindall s10dal@elrepo.org --- This issue also applies with the recently updated amavisd-new-2.8.0-8.el6.noarch package installed.
Removal of localamavisd (see above) SELinux module causes amavisd to allow mail with an attached, zipped exe file to be delivered.
Reinstallation of localamavisd allows amavisd to correctly identify and quarantine the mail.
