The truth is that most modern MTAs have a reasonable default timeout on
email queued due to failed delivery attempts, anyway.  That's why I
specifically mentioned that last bit.

For a more extensive discussion of secondary MX issues see:

    http://jimsun.linxnet.com/misc/postfix-anti-UCE.txt

and look for the section entitled "When There's No Point To A Secondary
MX," near the bottom.  (No sense in repeating it here.)

My ISP for my home 'net connection did that for me right off.  And it
was all right--for a while.  Then the spammers started exploiting
secondary MX' on a large scale and I asked my ISP to remove that
