RE: How is SPF different from RMX?

I have asked repeatedly for a specific fault in Sender-ID. The only response
that has been given is a repeat of the vague claim that the protocol is
flawed and cannot work.

The fact that other people have proposed broken solutions to the spam
problem and have failed is irrelevant. None of the specific reasons for
failure appear to be relevant in the context of Sender-ID.


The requirements that Sender-ID seeks to meet are very precise. It provides
a means by which legitimate users of a domain name may authenticate
themselves to recipients in a limited set of circumstances. It is understood
that failure to authenticate cannot be considered proof that the sender is
false.

Other authentication mechanisms to meet an extended set of circumstances are
pending completion of this work.
