We added two remote nodes to our exchange 2010 DAG. For some reason there are message in the remote servers that are stuck in the smtp relay queue pointing to one of our home office servers.
418.104.22.168 Cannot achieve Exchange Server authentication. Attempted failover to alternate host but did not succeed. Either there are no alternate hosts or delivery failed to all alternate hosts.
I tried adding a receive connector for the remote servers, specifying both the home office network and the remote office network then allowing Exchange server authentication and anonymous.
