Close. Since I actually have nine "base" domains with variants, it's
# getent group
dom1:user1,user2
dom2:user1,user3
valid: user1@???, user2@???, user1@???, user3@???
invalid: user3@???, user2@???
And the set of which base domains have which TLDs is not complete. I
have all but one in .org; it and three others are in .net; and one is
in .us.
Thanks,
Jim
