Some time ago, I read about a Listserv feature (could be 1.8d) that allows a person to sub or unsub to a list by simply sending a message to a hashed address that includes the listname - something like: [log in to unmask] The server then taks the user information from the message headers and ignores any other information in the message. Try as I like, I cannot figure out the syntax for this special list "address." Also, just how many specialized addresses are there with Listserv software? I know about and use on a regular basis listname-request@, owner-listname@, and simply listname@ - what others are there besides these and the above "sub" or "unsub" addresses?
