So his MTA is EHLOing as mail.bobhoffman.com mail.bobhoffman.com resolves to 72.35.68.59 (matches the incoming ip) 72.35.68.59 reverses to bobhoffman.com (which doesn't match the host)
As far as I can tell this will hurt his score. Or am I missing something?
I don't know enough of the specifics of yahoo's scoring.
However, in my experience it is better to have your sending host IP have a resolvable PTR record than not. I'm quickly loosing track of this thread, but it appears bobhoffman.com has that covered.
As an aside, it would be my expectation that forward/reverse DNS literal matching wouldn't be scored highly (if at all) simply due to the common use of virtual hosting and the like, let alone the split in/out mail architecture already discussed.
