um, excuse me, but they don't do that. I'm the sendmail sysadmin for our 
site, I spend a fair bit of time reading mail logs, and if they did that 
I would see it. Furthermore, they'd be failing to follow the RFCs if 
they rejected based on a temp fail.

What they do is confirm your email address at the outset when you 
subscribe. You get an email and you have to respond to it. After that, 
your email submissions have to match what you subscribed with. That 
initial exchange is not so very time critical as to be killed off by 
greylisting. They resend after a bit, and you reply to that. It works.

It's pertinent to the original poster and to Kern's response to the 
original poster.
