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.
