I know that Yahoo does greylisting, and we often have a large queue 
backup as a result of mailing lists with a lot of @yahoo.com addresses. 
As long as you keep retrying I find that they do eventually get through.

Between greylisting and sender callback verification, it seems that 
overall email delivery is increasing in latency and decreasing in 
reliability.
