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.
