Send me an email at geek () stovebolt com, 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 - smtp.vt.edu. 192.82.162.213 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. Paul Schmehl (pauls () utdallas edu) Adjunct Information Security Officer The University of Texas at Dallas http://www.utdallas.edu/ir/security/
