Back to the PTR RR:
$ dig +short MX bobhoffman.com
10 mail.bobhoffman.com.
^^^^^^^^^^^^^^^^^^^^
$ dig +short A mail.bobhoffman.com
72.35.68.59
$ dig +short -x 72.35.68.59
bobhoffman.com.
^^^^^^^^^^^^^^^
mail.bobhoffman.com != bobhoffman.com
This may not be your main problem, but it certainly isn't helping
matters. Yahoo seems to be pretty picky on reverse DNS. I had a VPS
running a mail server where the PTR matched the host. I was relegated
to yahoo's spam folder until changed from the default PTR which looked
mildly like a dialup.
