I can't remember where I saw it first; it may have been on a
spam-related mailing list where port 25 blocking was being discussed, or
it may have been from building my own RPMs for sendmail, as sendmail has
come configured with an MSA daemon on port 587 "out of the box" for some
time now (since 8.10.0 I think).
