As others have mentioned, there are reasons (internet congestion, for
instance), but I gather what you really want to know is whether
there's something unusual about my configuration that would cause this
to happen. The answer to that is no. I'm running sendmail on a
gentoo server. No crazy configs, I don't run my own DNS, and frankly
I don't know why my sendmail would try high MXs before low ones, but
apparently it does.
I'd say any system that requires you to investigate to this extent
with blocked senders on a one-on-one basis has problems, and I would
once again recommend that you test any system by tagging mails before
actually rejecting them so that you learn about false-positives rather
than assuming there aren't any unless someone reports it (which would
be hard to do, since you're blocking them).
Since this is now way OT for the SA list, I'm not going to respond on
the list anymore, and since you're blacklist rejects my emails, I'm
guessing this is the end of the conversation for me. Good luck.
