Upgrade to pfsense 2.2 broke postfix forwarder

[snm777]

I had a co-worker upgrade a production firewall from 2.1.5 to 2.2, running a working configuraton of the postfix forwarder on 2.1.5.  Ater upgrade, postfix won't start.  I re-installed the package JIC, no luck.  The error I get is

php-fpm[76649]: /pkg_edit.php: The command '/usr/local/etc/rc.d/postfix.sh stop' returned exit code '1', the output was ''

I also see about a dozen of these:
postfix/master[88954]: warning: /usr/local/libexec/postfix/qmgr: bad command startup – throttling

I have compared to an identical working config and haven't spoted any differences.  A quick seach of the forum didn't yeild any clues, can anyone tell me what I should try next?  What information I might need to include to help figure that out?

Well, crap.  I found out my issue is this:

Apparently pfsense 2.2 security sysctrl option does not allow non root users to listen on low ports - and /var/spool/postfix is owned by the postfix user.
