It seems I perpetrated a vile and offensive error in sending a subscribe request directly to the list.
I don't get offended, I just save the subscribe/unsubscribe message in a special folder that I will use to train a learning algorithm to recognize these kinds of requests. Then, I will create a program that detects these so that mailing lists everywhere can automatically bounce messages back to the sender with specific message like "please send un/subscribe messages to fubar-request@node.com". In other words, thanks for your example. Anyone who sends me examples will benefit this project. (But don't send examples from cypherpunks--I already get them.) If anyone has suggestions for implementation that maximizes applicability (e.g., I could write a C program that reads stdin or a named file and returns a status code), please let me know. Paul E.
