You have things ordered slightly different than in the example, but
that should be OK in this case, I think... The important thing is to
reject unknown domains prior to unverified recipients... Postfix does
know the "destinations" it handles mail for, right?

While testing, if this is a "live" system... it might be wise to do a
450 instead of a 550;-).

You might want to skip this initially, so comment that out and do a
"postfix reload"... Seem if it starts cooking...

Worst case, if you have ... interresting transports, you might need
apply the last parts of the instructions... Hopefully, you don't.
