Not entirely.
If other people use your remailer also, and you have latency, they'll
see n messages going into your remailer, and n come out. There will
be log2(n) entropy added, they won't know which of those are from you
and which from the other users.
Flooding attacks might make the situation worse, say you wonder if all
of the messages apart from your own are from the attackers, and that
the purpose of these messages is to flush your message out of the
mixing pool.
