[Declude.JunkMail] Setting a test for a specific domain

[Doris Dean]

is it possible to set a test for a specific domain ... rather than using the whitelist (as I recall there is a limit to the number of whitelist tests that can exist) so instead could I set up a test where the domain could not fail? If yes what would it look like .. I am using the declude standard version ...   TIA Doris
