Skip's right: they're indeed random gibberish, to frustrate stupid "exact
match" filters. Random characters often appear at the end of Subject lines
too, for the same reason.
All they do for us is bloat our database with random strings; it's one of
several reasons that a learning database needs a policy for "expiring" words
over time (else it would grow without bound).
