I think it might be helpful to set up DKIM as well. The standard prohibits differentiating between unsigned mail and mail with a failed signature, but you are allowed to decrease spamminess scores for a successful signature verification, and also for From alignment (aka DMARC pass). (Yes, I believe that Yahoo conforms to standards in this respect, though I can't be sure.) The FAQ as mentioned by Mark already (fastest consult in the West!): http://wiki.list.org/x/4oA9 A useful tidbit from that FAQ: Yahoo's feedback loop is at http://feedbackloop.yahoo.net/index.php > X-IronPort-Anti-Spam-Filtered: > true I hate IronPort. My employer uses it and enables [SPAM] subject tags, so it's *really* obvious that about 40% (!!) of spam is *not* caught, and on the other hand about 15% of ham is tagged SPAM or SUSPECT SPAM. Why bother?
