2 things:

- You should take this to a list / forum where it is more appropriate to
discuss setting that kind of things up. postgrey has a mailing list and
as you learn to handle Postfix you may subscribe to the Postfix list.

- You can be very sure that your regex in postgrey_whitelist_clients is
wrong and does nothing useful. Have you ever seen a host with DNS name
".com"? Would you ever? No, of course not.
You define the whitelisted client names to start with a dot and to end
with the TLD right after the dot.
