Actually ... the only thing in the hold directory is the 
razor-agent.log. Nothing else. There is also nothing in the incoming 
directory either. The server is not delivering any mail now. Though I do 
not see ANY errors in the logs. I can send myself an email and I see it 
being delivered to my maildir. But it will not deliver it.

Currently, the /var/spool/postfix directory itself is owned by root:root
Inside this directory, most everything is owned by postfix and group 
root but is only rwx for user only.

So, if I create the needed folders in here and set them up as the same 
permissions ... should that work?

See above.
