Terry Zink: Our latest outbound spam mitigation technique
“Since we are a mail filtering service that acts as a relay, we are not in command of validating login attempts. Thus, all mail going through us we have to assume is already validated upstream. However, we know that this is not the case because piles and piles of spam passes through us all the time every single day from multiple different compromised accounts. Therefore, we know we have an outbound spam problem and that we are relaying it, the problem is that we do not control the login process. I should say that more accurately that piles and piles of spam attempt to pass through us all the time. For you see, in the pass few weeks we have been experimenting with a new brand of outbound spam mitigation.”
