sender_verify_except_hosts specifies those *remote* hosts for which
no checking of incoming senders is done on messages they send to the
local host. It does not specify domains. If you want to specify a domain
for which no verification is done, you can't do it directly, but you can
easily fudge it by (since this is a local domain) inserting as your
first director something like:

allow_any_verify:
driver = smartuser
domains = domains:for:which:you:want:to:do:this
verify_only
verify_sender

However, if it is easy enough to maintain a list of those local parts
which are not in your passwd file but which are permitted, it would be
more secure to verify them explicitly, using an aliasfile director.
