Yes. MMDF. Thus Plc (Demon Internet) -- you'll hit problems whenever
you deliver to one of the UK's largest ISPs. Perhaps not so good for a
UK academic institution. Same goes for Demon NL [*].

Unfortunately, yes. At this time. Demon is working on migrating away
from MMDF; this is public knowledge. But it's still there, receiving
any mail sent to a Demon customer. Uhm, the best I can recommend, if
you feel that this is an issue, is to raise it as an issue with Demon
and to get those Demon customers whom you need to communicate to do so.

If a server doesn't advertise 8BITMIME, any server which _does_ have
8bit content, should downgrade the content. Exim doesn't have the
ability to do this. Therefore you'll be introducing breakage and
corruption by turning the feature on.
