Massive problems with email delivery to Yahoo and AOL today, they share a mail system on the back-end. Microsoft issued advisory 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. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Blue Stream Fiber, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ _______________________________________________ Outages mailing list Outages@outages.org https://puck.nether.net/mailman/listinfo/outages
