What do you know, my hosting provider has a 2 second preconfigured thing
for just this problem... so now, exim is running a copy on 587 as
well... I don't mean to be a hassle, but I'm not seeing how to redirect
my client to use that port now though... I thought it was in Bill's
earlier message, but I can't seem to distill it from the server settings.
