Massive problems with email delivery to Yahoo and AOL today, they share a mail

EX719348 last Thursday for their IPs being included in some DNSRBLs, and I
still see some of their IPs on the Spamhaus RBL
(40.107.102.127) but I'm not sure if that's the root cause.
Spamhaus has what they call a "Token" listing for that space. That means
it's not present in any of the DNS zones (so no blocking should be done
based on the listing), but it's in the back-end DB for tracking purposes
and to generate a notification to Microsoft that they have an issue they
should deal with.
