A year or so ago, I would have mentioned Yahoo! Groups, which used to have
(or seem to have) a one-strike-you're-out rule: one failure tripped the
recipient out of receiving email from Yahoo! Groups and into being able to
read group messages only via the web.

But that seems to have changed: Yahoo! added a bunch of outgoing servers we
didn't know about, and the resulting greylisting 4xx messages didn't seem to
hurt the recipients. (We had the known Yahoo! Groups servers white
listed...we've added the new ones we've seen.)

And a connection failure might not have triggered the same rule anyhow.
