  It seems to me that the optimizer is working as intended.  Either the
costs are not accurate or the mail actually should go through A!B!C.  If
Z is actually cheaper than the data base should be changed.
  If you decide that you want to use Z anyway (maybe to avoid making A,
B and C paying for your mail) than what is the harm in reducing the cost
of the link to Z?
