Yahoo Mail problems ? (queue issues in general)

Anyone else seeing Yahoo mail queue up today ? Some of their servers respond in about 10secs with the HELO banner, most others take more than 2m. Because of the recent increase in SPAM, I was looking to reduce the wait time for the initial HELO to 2m from 5m. However, the RFC calls for 5m on the HELO and another 5m for the MAIL command.

Having a process block like that for up to 10m seems a bit excessive to deliver one email (and its probably a bounce to boot!). What are others doing? This problem seems to becoming more and more acute.
