Please don't top-post.

For customer domains, either require a valid recipient list, 
or use reject_unverified_recipient to let postfix build a 
recipient list for you.

Use a check_recipient_access table to limit 
reject_unverified_recipient to only the domains you don't have 
a list for.  There was a discussion about this just a day or 
two ago.
