Evidence: Ah.  The other day, when I was doing *my* test, I tail -f'ed the 
mail log while sending stuff, I kept seeing the same delivery attempts over 
and over.  

Evidence: When I sent my own mail from my server to all wind at blu.org members, 
there were many dozens of failures.  

Theory: What is happening is that there are so many failure attempts on the 
WIND list  (and maybe others) that are waiting their 4 days before removal 
from the queue, that the mail server is being starved so it can't get *good* 
emails out fast enough.

Maybe we could copy the mail queue somewhere else and wipe it out, then slowly 
(one a minute) inject queue entries back into the live directory from the 
backup.

We should also do a validation of email addresses on the list:
- Remove the WIND list from the aliases table
- Make a temporary WIND mail account
- Send a single individual message to each member
- Cull the failed addresses from the mailing list (many dozens)
- re-establish the list
