But for how long?
The interesting thing about this technique is that it allows netvision
to pass the RBL tests, because they don't guess correctly the right user
name. As soon as that is fixed (i.e. - as soon as spam starts going
through them), your mail is going to be black-holed by people. This will
happen regardless of whether you are working from within the netvision
IPs or not.
