> Got a list of their outbound relays?
Haven't tracked it to be honest. I'm whitelisting based on combination of
both sender and reverse DNS name. My understanding is the first box that
tries to talk to you, if it fails for any reason (including greylisting),
they punt it to a different box for the slow deliveries. That box,
immediately tries once as well, then sits on the message for hours.
My number one user of course was affected by this. Since I'm married to
such user, I actaully paid attention.. :-)
