This is curious. You are hashing the 'incoming' queue but Mailscanner is
queueing the message in /var/spool/postfix/incoming/C096D42C55 instead
of /var/spool/postfix/incoming/C/C096D42C55.

I don't know if this is the problem or not, but hashing 'incoming' is
thought to be unnecessary, see
<http://www.postfix.org/postconf.5.html#hash_queue_names>.

I suggest removing 'incoming' from hash_queue_names or maybe removing
hash_queue_names entirely and going with the default and reloading Postfix.

If this fixes the problem, it's probably actually a MailScanner bug.
