You don't have to accept such mail, or if you, you don't have to forward it to the internal system behind the SSH port forward. And if nevertheless you do, you can arrange to not forward it back from the internal MTA. > http://skidrowstudios.com/mta/cmx01-logs.txt Post all relevant data in the body of your message, I am not inclined to chase them down by switching to a web browser. Loop breaking is simply a matter of knowing which system is responsible for final delivery of a given message recipient. Don't forward mail that for which the input MTA is expected to be the final destination. -- Viktor.
