Well the  solution to the problem  is easy. The underscore  is an invalid
character in  DNS addresses and I  can't believe people wrote  and sell a
SMTP that actively  uses it. It only works when  you are fortunate enough
to travel  along a  mail path  where all mailers,  SMTP servers  and name
servers happen not to  enforce the RFC. The same goes  for the hash sign,
so Compuserve  just translates an  invalid address into another  one. You
can't  mail to  these  addresses  from a  VM  system  because IBM's  SMTP
enforces the RFC.  LISTSERV itself doesn't mind, but it  won't make it to
SMTP. The  only solution is to  change cc:Mail or at  least Compuserve. I
know  what you  will  say  about the  difficulty  of  this solution;  the
alternative is to change the standard and wait 10 years.
