Hum, we haven't done so explicitly yet... but since we just launched, and our email traffic isn't that high, I don't think the chances of 2 random people typing in the same bogus email address. I have the list of all bounces Emails and I will take a look at them. Will also take the recommendation to implement this check soon. Besides that, any other recommendations? Is this just a Hotmail issue?
