I see this 'not greylisting' and we are a fairly tiny operation (I had
about 20k outbound emails last week) and don't allow people to
autoforward email from our servers. I find that yahoo.com destined mail
stays in the queue for about 48 hours, with a 1,1,2,4,4,4,4,etc... hour
retry.
As I tend to peak at a couple of hundred mail in the queue when things
get busy, it's not a problem, but can see where it would be for larger
operators.
