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.
