Yahoo deferrals are quite common. They throttle inbound connections,
so if you have a bunch of Yahoo deliveries at once, they defer you
with a URL saying that they have had user complaints about you. But
that's not the case, it is just throttling. You'll find dozens of
posts about that issue in this list's archives.

Um, the default setting is 100. Why did you set it at 10? Don't mess
with defaults like this unless you have good reason to do so.
(Okay, we CAN guess that a process limit of 10 might cause problems
like this, disregard what I said at first. :) )
