So I have a user that is sending out mail to a number of Gmail accounts but one of them bounces with this error The sender does not meet basic ipv6 sending guidelines of authentication and rdns resolution of sending ip This has not happened to anyone else and I can email to my Gmail account fine. The recommended fix is to create a reg key and disable IPv6 which I am reticent to do. Exchange 2010 SP3 on 2008R2, I do not have a static IPv6 address on the server nor have I ever noted one in our MX records. Anyone else ever run across this?
