We have a situation where we/many of our customers are unable to receive
email from Yahoo due to broken DNS, which really doesn't look broken. As I
don't have error numbers, just undeliverables, automated support is not
useful. Off-list is fine, but posting a real honest-to-gosh-real-life
contact to NANOG would probably be awesome to more people than just me 
Thanks!
