Bingo. Thanks. The problem has nothing to do with +. His server is
rejecting the email because it doesn't like how my DNS entries are
set up. It was coincidence that the first user with a + in his address
was also the first user from that finicky destination server.

Mail directly from me to him doesn't use the same source domain,
so it didn't hit the server's validation check.
