Yes, I believe that is true.
I made it sound like this is just a testing issue in my earlier
message but I see 2 or 3 attempts per week by real spammers to
exploit this.
FG> How can xmail be altered to prohibit this functionality?
Actually I do filter on the "%" sign in the RCPT TO of the
envelope but you don't need to do that really.
All you need to do is set your server for no mail relay and make
certain that if you do have IP's allowed to relay that they are
not backup servers.

FG> Am I right?
I think I misled you. There really is no danger if you insure your
sever is not an open relay.
