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."
