We are using a locally built Postfix (Postfix-2.8+ is required to support postscreen and CentOS only provides 2.6.6)

Re: SELinux. Do I just build a local policy or is there some boolean setting needed to handle this? I could not find one if there is but. . .

Are you sure you are really up to date on CentOS 6?
https://rhn.redhat.com/errata/RHBA-2013-1598.html is old and meanwhile outdated. I don't have such a problem with the Postfix 2.11.3 package from ghettoforge on a current CentOS 6.6.
