I'm unclear as to whether your situation is:

1) Mail to user at domain.com shouldn't be accepted anywhere.

2) Mail to user at domain.com shouldn't be sent to mail.domain.com, 
which doesn't know what to do with it, but should instead be sent to 
unknown.domain.com which hasn't yet been mentioned.

Assuming that it's situation #1, you need make sure there aren't any 
MX or A records for domain.com.

Once the MX for domain.com is removed, then mail to recipients at 
domain.com will be automatically bounced with a "host unknown" (or 
similar) error message.

If it's actually situation #2, then there are any number of 
approaches that could work. :-)
