Not sure why this is a MUST NOT. If people are dumb enough to use a
mixed list in a broken way they get what they deserve. What's the
justification?
Matt.
This isn't just broken lists it's broken software. Not all software
which uses DNSBL's differentiates by returned response.
Valid point and a separate section on client configuration/usage or even
a separate RFC would be a good idea.
