It shouldn't hard with one clarification to the rule above: if a
remailer only wants to receive mail from other non-stealth remailers,
then it will require client authentication.  The reason for this is that
the server must have some prior knowlege of the client against which to
test the client's authentication.  The existing remailer keys should be
fine for this.
