And, e.mail.de has no soa RR as well. $ dig e.mail.de soa +short gets nothing. I am guessing yahoo is blocking the specified subdomains, not all. As a comparision, I sent another mail from my alumni email, alumni.nd.edu. This is a real zone, has soa defined. $ dig alumni.nd.edu soa +short ns1.nd.edu. dns.nd.edu. 209 10800 3600 1209600 900 And the message was delivered to yahoo successfully. Anyway yahoo should not reject a message only b/c its domain has no SOA. regards, Ken Peng _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
