Subj : Mail for unknown points To : Kai Richter From : Alan Ianson Date : Mon May 10 2021 12:59 am Hello Kai, KR> Yes. Inform the "from:" sender that the point does not exsist. KR> A netmail tracker would be your friend. KR> Very interesting attack scenario. KR> Netmails from unknown points to unknown points would create a pingpong KR> war between two trackers. :-) That is what was happening. I've never encountered that before but "route hold nopack 1:153/757.*" below my other points has stopped that from happening.
