Thanks Glenn.

However, I don't believe this is enough.

This is an extremely egregious flaw. Inserting an inappropriate string like
"i-did-not-set--mail-host-address--so-tickle-me" in Emacs users' email
messages, without asking their permission and without informing them, is
unacceptable.

If the "fix" is to document the danger in NEWS, then it should be in the
sections on Message and Gnus. No one is going to think to look under
`system-name'. After all, even the person who made this change to
`system-name' clearly didn't make the connection that it would effect
users's Message-IDs; there's no reason to expect a casual email user to
make that connection.

Well, that's just the suffix of the Message-ID. The full thing would be,
for example, something like 877ff9dc26.fsf <at> moondust.localhost. Clearly
not unique like a GUID, but having a high probability of uniqueness.
