Personally, we've looked in to it. We tend to agree that AOL's position is somewhat aggressive since their techs are usually behind the time and don't support their own new technologies well. But, political opinions aside, we were leary about implementing it because, frankly, we were afraid of the possible negative impact. So, we have relied on MimeDefang to do this check for us..
However, as time has worn on (and the amount of SPAM has blossomed), we have started testing this hack on our in-house testing server. Hearing of your experiences does make me feel a bit better regarding the patch, too. Do you have any stats on how many connections this has prevented?
I've been using it on and off and I'd like to say I am simply AMAZED at the number of domains with horked up DNS, but considering the temperature of today's "hire the cheapest admin we can" attitude, I'm not.
I just turned it off today after having it on since like December to see what happens (actually to prove to the person who asked me to turn it off that the people he wants email from should just fix their damn DNS)...
So it definitely has its blessed-cursedness...
It stops a lot of spam. It stops a lot of legit email.
Can't say much more than that.
I have some stats... they're tabular so... for what it's worth

Look at the noDNS and ForgedDomain
