  I have an Essential Business Server 2008 Environment.
  
  Currently Inbound email flow is fine with all messages being received. Outbound is however sitting in the mail queue waiting to be delivered.
  Next to the Edgesync queue the error is
  "451 4.4.0 Primary target IP address reponded with: "421 4.4.2 Connection dropped." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts."
  
  If i restart the HubTransport service then the queue clears and all messages get delivered, however i am then left with the same problem of the mail queue filling once more.
  
  I enabled connection logging but this does not give any clearer indication of the problem (attached partial log below)

  The only system changes recently that may have affected this, is the installation of Microsoft DPM 2007. The agent has been installed on the Messaging and Security servers but has not been used to backup up yet.
  This was installed per the technet guide at http://technet.microsoft.com/en-us/library/cc512491(WS.10).aspx
