Yup, GTUBE is perfect for content filters, but I'd be nervous about  
putting it into a DNS query, as some of the characters are unfriendly  
to naive stub resolvers.

But I've found GTUBE *extremely* useful for sanity checking my  
spamassassin installation, and that's the main reason that I think  
that something that really is a domain, and so which can be used as  
part of a test message to check an entire filtering system in addition  
to being used as a liveness check for lists would be valuable.

Cheers,
   Steve
