Yahoo is saying that means the domain does not send email - basicly its

I think you are correct, and I don't want to argue with you, but the RFC:
http://ietfreport.isoc.org/idref/draft-delany-nullmx/
That is NO RFC. That is an internet draft produced by one particular party.
Says "This document formally defines the "NULL MX" as a simple mechanism by
which a domain can indicate that it will never accept email."
"accept email" != "send email"
It's too bad one has to read the whole RFC to get the picture that, in the
context of NULL MX "accept email" == "send email" by implication.
Would have been clearer to me on first read if: "This document formally
defines the "NULL MX" as a simple mechanism by which a domain can indicate
that it will never accept email and therefore (implies?) also does not send
email"
Could you define what "domain does not send email" means?
