Subject RE: Immediate 550 responses to illegal sends
Date Thu, 18 Apr 2002 22:15:50 GMT
I have researched this extensively. Danny is totally correct. MAPS RBL and RSS will only list
a relay *after* they
receive relayed mail. (Orbz as well) Therefore there are no concerns. 

I have in fact gone out and proven this. I'm going to publish my results soon, first to Danny
for validation, and then
on to the group.


Ps. Sorry for ever doubting you ;)

James doesn't do this at the moment, but there are plans to make it do it.
You should also be aware that 550 allows spammers to harvest valid addresses
from your server.
