Noel,
Guess I'm confused. I have a relay_recipient and recipient_access files listing only valid user's email addresses for my company.
ie..
relay_recipients
bg...@lmtribune.com     any_value
bi...@lmtribune.com     any_value
bjohn...@lmtribune.com  any_value

recipient_access
bg...@lmtribune.com     permissive
bi...@lmtribune.com     permissive
bjohn...@lmtribune.com  permissive

and nothing in virtual_alias_maps. I just seem to be getting hammered with yahoo.co.jp and wanted to block .co.jp or even .jp.

Putting info in putting .jp in access_client, sender_access or client_access doesn't seem to stop it.
Sorry for my lack of understanding.

In looking at the file in xxx/deferred, my mailserver is trying to return an undelivable message and it looks like there is something wrong with the site. " said: 557 Invalid routingNC request - domain in BLACK LIST." Basically I think the site is a spammer and they are blacklisted. How can I blacklist the .co.jp so I don't receive their message to start with?

You're focusing on the wrong problem.

1. Don't accept undeliverable mail to start with. That will cure most of the problem.
  - don't use wildcards in relay_recipient_maps
  - don't use wildcards in virtual_alias_maps

2. Use zen.spamhaus.org.  That will cure most of the rest of the problem.

smtpd_client_restrictions =
  permit_mynetworks
  reject_rbl_client zen.spamhaus.org
