Is it because they are using compromised machines, and the 'limited' time is the time before this is discovered by the compromised host's admin? > - If he realize, that your MX is answering slow - you'll get a "spammers > penalty" You mean, they are 'scoring' the receiving MX in much they same way ASSP is scoring the sending MX? > IMHO - ASSP is great to block spam - but I think we should fight against > the spammers as much as we can in a legal way. I think you may have said this the wrong way - it implies that ASSP is not legal.... I thought it was completely legal....or was it in reference to the previous paragraph?
