Yes. We might end up having to consider whether to attribute
semantics to the <display-name> as a way to solve the
problem. Let's assume that 20% of IETF mailing list
subscribers use a "p=reject" domain name in the "From:"
field and that they are no longer allowed to post messages
to the mailing list because of the policy advertised by that
sending domain. What should the mailing list moderator do in
response to complaints from those subscribers?
Send them a canned message stating that the only solution
available to them is changing to a different From address that
does not have this issue. What else can they do?
Note that this is very similar to one of the options for an
SMTPUTF8-capable IMAP or POP server to take when the client does
not present itself as able to accept should messages, i.e.,
"there is a message you could receive (with SMTPUTF8 POP/IMAP)
or send (with a different mail provider) if you were running in
a different environment, but, with your current environment, you
lose."
