New policy for Pop-before-smtp daemon

[David Hampton]

Here's a new policy to support the pop-before-smtp daemon from
http://people.FreeBSD.org/~sheldonh/popb4smtp-nodb.tar.gz .  I'd
appreciate any feedback on these files or tips on how to write better
policies.  Thanks.

David

P.S.  This policy is based on the selinux-policy-strict-sources-1.22.1-2
rpm on my FC3 system.
