Hello, ever since I installed my new SBS 2011 server last weekend I can't send to any yahoo.com domain. I can send to EVERYONE else (hotmail, aol, gmail, and every other doamin). I keep getting the message below. I have send several emails to the postmaster, filled out the whitelist form and the ulk sender form (even though I am not a bulk sender) and have not heard back from yahoo. We did not change our IP address, we are not on any blacklist, we have a reverse dns entry, and I created an spf record yesterday. Is there anything else I can do on my end? Yahoo isn't responding. This is nuts!
