On our system, UNIX 4.3 with Berkeley sendmail 5.65, Internet links
only, messages are marked deferred if they are not successfully
delivered and the mailing process determines that it may be
successfully delivered on future retry.

e.g. A network link was down so the connection attempt timed out.
     The remote host load was too high so it refused connection at the
     time. 
     The remote host was "slow" so our mailer decided that it was
     dead.
     The remote host was down.

In our configuration, deferred messages are retried hourly, with a
three day delay before "bouncing" a message as undeliverable.  You
will have to ask your system administrator (or the postmaster at the
relay point, if it was returned from some other location "part way" to
your destination) if you want more information.
