Your postfix user cannot read your config file/directory, likely. Test with
su - postfix -s /bin/bash
and then use cd and "ls -d" to try access /etc/MailScanner ... and
ultimately reading MailScanner.conf with "less" or something.
When using an MTA that runs as an unprivileged user, permissions is everything.
Also check that you've either turned off SELinux or amended it so that
it doesn't get in the way:).
