Perhaps more of the SMTP server's "recipient valid" check could be
done in the trivial-rewrite "resolve" service.
This would add one query after the recipient address class is
determined, to query the "valid recipient" tables for that address
class.
Then, those queries in the SMTP daemon could replaced with a "resolve
address" call whose results are already cached in the SMTP server
process.
