Yahoo! is currently handling somewhat over 300,000 delivery attempts a
second[1]. You don't need to increase the average cost of a mail delivery
(either by increasing the cost of a delivery attempt or by increasing
the number of delivery attempts per message) by much for it to add
up to significant costs.
I believe it, but to be fair, they also have not come forward to indicate that
this is hurting them. Thus, I have to conclude they can handle it just fine.
