The host, pair.com, did not find this acceptable and I lost a
week of mail while on vacation. I've since written a maildrop
script which uses the same pre-cdb to-file/from-files as tmda.

maildrop runs first in my .qmail files and tmda next as needed.

The biggest problem was/is mail sent to entirely bogus addresses.

Time will tell if the host finds this new solution acceptable.
