Umm.. John?  Actually, there's a few more issues than just 3.

This  is  2 issues.  The  question  asked is  the specific question of
whether you  must act as a  relay for  2  other  parties when you wish
not to.  I   don't think  anybody disagrees  that AOL has the right to
refuse to act as a  mail   relay.  I don't  have  a problem with AOL's
refusing to  act  as  a relay  for 2  3rd  parties.   I don't   have a
problem  with AOL  refusing    to  accept any email   from a list   of
known spam sites (AOL  has     a  list of    such sites on the web  at
http://www.idot.aol.com/preferredmail/).       I  don't     have     a
problem  with AOL     rejecting   source  routing   from  known   spam
havens.

The second issue is  what your  answer  actually addresses -  do sites
have a *generic* right to reject arbitrary mail (not just relaying for
2 other sites, or other specific case), and if so, what grounds are
considered justifiable?

I *do*  have a  problem with their   refusing  to accept   mail merely
because it had  passed through a  relay sometime  before they received
it, on purely syntactic grounds  that the RFC's mandate support   of.

Ahh.. but AOL is rejecting mail  *PRECISELY* because sites have chosen
one form over another.  That's the crux of the problem.

AOL set up Preferredmail  as part of the  CyberPromo  lawsuit(s).  Are
their  users aware that some *OTHER*  mail  may be getting rejected as
well, with no warning and no option for the users?  It sounds like the
users whos mail is being rejected  would have even  MORE grounds for a
lawsuit than CyberPromo did....
