Format Clarification

I need a clarification of the format to thrash some mail that is NOT addressed
to one or more designated addresses at three domain names (okname1 is legit
at all domain names, etc.)

Before I throw the switch on the (modified) recipe, I'd rather be safe than 
sorry.
Did I get it right?

Thank you.
