On Debian/Ubuntu, MailScanner (at least some versions) doesn't start
Postfix. You need to start both MailScanner and Postfix and you need for

header_checks = regexp:/etc/postfix/header_checks

in Postfix and

/^Received:/ HOLD

in /etc/postfix/header_checks. Postfix receives the mail which always
has at least one Received: header so puts it in the HOLD Queue where
MailScanner picks it up.
