+===SBS 2011===
+We haven't tried this here, but a user with SBS 2011 said he fixed this problem as below:
+   The cause of the problem was SBS 2011. This comes with Exchange,
+   and I had partially set this up before giving it up as too intensive.
+   The ESMTP service was running as part of the client hub for
+   Exchange, so disabling the hub services within Exchange Manager
+   Console fixed the problem.
