Send me an email at geek (at) stovebolt (dot) com [email concealed], and I'll tell you.

I'm not sure what you mean by "split inbound and outbound", but any
outbound MX host *should* be listed in DNS. You only list one - is reversible, so it would get points for
being honest about its IP/hostname, but it would lose points for not being
listed in DNS as an MX. The overall score would determine if the mail was
rejected, but I doubt that it would be.

Easy enough to tell. Send me mail.
