CentOS 6 MailScanner & Postfix issues

[bradley at stygianresearch.com]

Good morning.

I'm setting up mailscanner/postfix on a centos 6 server that I'm building to replace a CentOS 5.7
server.

For Email that send to the server externally (different host) is lost.  Postfix receives it,
mailscanner scans it, and then nothing.  Here are the messages in syslog:

Thats it.  Postfix doesn't get to ever see the scanned email and its lost.

Now, if I send Email to the server internally (same host) mail gets delivered.  Postfix recives
it, mailscanner scans it, and then postfix delivers it:

I'm currently running selinux in permission mode to make sure selinux isn't causing any issues. 
If MailScanner is stopped and just postfix is running, mail from both an external and localhost
are delivered fine.

Its just that when MailScanner is running, mail from an external server just disappears.

Does anybody have any suggestions or point me in a direction to go to?  I've been using
MailScanner for years on a centos57 box without any issues like this.  I even switched from
sendmail to postfix on centos 5.x without an issue like this.

Thanks in advance for help.
