  uucp connections are NOT the same in both directions. For instance,
many sites call sixhub (a) when they have mail, or (b) at long spaced
intervals. Thus from that site to sixhub the cost is DEMAND, while the
other way it is WEEKLY.

  And some site call ONLY on demand, which make the cost back to them
DEAD, since the average time between calls may often be longer than the
expiration time for mail.

  This happens when one site is picking up the phone bills, and explains
why you often can't return mail by reversing the path.
