Re: MTS transparency and anonymity

Bruce,

I think you're making this too difficult, by drilling too far down into details at this stage.

if anonymous(_at_)[] doesn't quite work, there are similar alternatives worth considering. among them are: anonymous(_at_)[0(_dot_)0(_dot_)0(_dot_)0], anonymous(_at_)[127(_dot_)0(_dot_)0(_dot_)1], anonymous(_at_)[127(_dot_)255(_dot_)255(_dot_)255], anonymous(_at_)[::0], and anonymous(_at_)[::1].

the problem with ""@[] is that, while valid syntax, the null local-part provides another excuse for something to break. the null local-part is not needed; it is sufficient if the domain is valid syntax but not a DNS name.

also there might be some merit in being able to differentiate between "anonymous" mail (where the sender chose to be anonymous) and mail from an unknown sender (such as sent from a web form). so we could have anonymous(_at_)[whatever] vs. unknown(_at_)[whatever](_dot_)
