[Exim] Re: Could idn-data be renamed to avoid spam?

i generally configure a majordomo list as

    foo: "|/usr/local/majordomo/wrapper resend -l foo foo-data"
    foo-data: :include:/usr/local/majordomo/lists/foo
    foo-request: "|/usr/local/majordomo/wrapper majordomo -l foo"

spammers have found that, though foo is subscribers-only, foo-data is a
spammable target.

what's the best way to block that?
