Eric, Your subscriber wrote in part: >I mark a message from someone or something I don't know as "unsafe." It sounds to me like he misunderstands the consequences of his attempts to mark messages that he finds suspicious. I suspect that he is actually putting in motion messages in the spirit of "no one here named Richard" directed to the listserver (rather than back to the sender), which therefore drops his subscription on the basis of these erroneous error messages.
