What is happening is that the vdom_alias envelopes to koivi@???,
which it should. However, koivi us a local user, and that is where I
want it delivered. Instead, koivi@??? is tested and gets routed to
spam@??? because there isn't a koivi:koivi entry in the domain
alias file. I do not want to accept mail addressed directly to
koivi@???.

What can I do to fix this?

Attached is my current config file with comments stripped.

This is what I am getting for debug output when I use the -bt option
with justin@???:
