I run (with others) mail.python.org, and we send assloads of mail to
yahoo!

What we did:

* set up DKIM for python.org
* subscribed to/set up Yahoo's FBL: http://feedbackloop.yahoo.net/
* made sure that whoever complains @yahoo gets unsubscribed silently
  within a jiffy.

We haven't seen any large scale deferrals for a long time now.

I also use:
yahoo.com  	slow:
in transport_maps with

slow      unix  -       -       -       -       -       smtp
in master.cf and

slow_delivery_rate_delay = 1s
in main.cf
