  Dave (and others),

  The "ECN problem" is unidirectional.

  VGER can't reach you when VGER calls your email servers,
  but your email servers can reach VGER!  (Or vger's MX backup.)

  That is, you CAN send to VGER even if VGER can't send to you!

  This is due to the way how the ECN handshake is done.
