Looking more closely, I see issues here. First, none of the mail I receive at yahoo.com has any X-Ironport-* headers. This is not Yahoo using an IronPort appliance. It may be your outgoing MTA or some other MTA in the delivery chain. Where are these headers in the context of the Received: headers. That will tell you which MTA added them. It appears your domain is pearwood.info and the IP address of the sending server is 150.101.137.129. There may be configuration issues around this. A server sending mail should have a rDNS PTR record pointing to a domain and that domain should have an A record with the IP address of the server. See <http://en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS>. The absence of this is a big red flag for many ISPs pearwood.info has no A record. the rDNS PTR for IP 150.101.137.129 is ipmail06.adl2.internode.on.net which does have an A record with IP 150.101.137.129 so maybe this is OK, but it is something to think about. Note that it is not necessary that the server's canonical name be the domain of the list. It helps if SPF permits the server for the domain and it does in your case, but if I had to guess, I'd guess the > X-YahooFilteredBulk: > 150.101.137.129 is the relevant header and it means Yahoo doesn't like your IP for some reason. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
