Asked Daniel Walsh what would be needed for a postfix2x policy. I am
wondering if we added the policy to the rpm with instructions on how
to install it would be ok?

So people in EPEL is looking at packaging a newer postfix for

as it has features they need. The problem though is with an selinux
policy for it as we would like to have it sit in parallel directories
and not conflict with the RHEL postfix. What would be the best ways to
make a policy for the systems (if it can only be RHEL5 oh well).
Just copy he existing file context files and change the path.
In RHEL5 you could just add the labels using semanage or better would be
to install a pp file You need a one liner for postfix.te. Then just
include a postfixnew.fc file with new paths. The type definition should
remain the same. You would also need to run restorecon on the paths
after you install the policy module.
cat postfixnew.te
policy_module(postfixnew,1.0)
cat postfixnew.fc
