True.
¡°SHOULD¡± (upper case) is actually defined in RFC 2119, which says:
3. SHOULD This word [¡ means] that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
So you have to have a good reason to violate a SHOULD.
I bet that particular MUA doesn¡¯t have a good reason (laziness of implementers is *not* a ¡°valid reason¡±).
But that is secondary to the fact that email was never supposed to be a
discussion instrument so nobody cares threading mail messages. [¡]
False.
Indeed, it doesn¡¯t get much falser than that.
Discussion lists have been around for more than a third of a century.
There is a proper way to participate in a discussion mailing list, and it probably is even written up somewhere ¡ª unfortunately, I don¡¯t have time to pull that reference up right now, but maybe somebody else could.
(This message is mainly intended as an example of how to reply to a message on a discussion list.)
