I've got messages queuing in Exchange to send to mail.msu.edu. On hold with ATS now. The msu.edu queue is listing this as the error: 451 4.4.0 Primary target IP address responded with: "421 4.2.1 Unable to connect." Attempted failover ro alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. So FYI if you have your own servers. Mail may be queuing.
