I would be curious to see if Yahoo rate-limits incoming mail with the
maildirsmtp method.  With only one connection open at a time, and that
connection being re-used serially (rather than establishing a new connection
for each message), it would not surprise me if their limits were much more
generous, or even not applied at all.
