Let the MUA choose a random value X, store it in a place that

Each time a MessageID is constructed the following algorithm
is used:
stem = date + serial + '@'
checksum = MAC (stem, X)
ID = stem + base32 (checksum)
Alternately, use public/private gets to do something similar. The
benefit there is that the public keys can be put into DNS, and
*anyone* can verify the validity of the Message-ID.
