I need to know what all the keywords are that can go in a list header, what the permissible values are for each, and what they all mean/do. I can't find a document in the base LISTSERV files that explains this for me. This is probably a FAQ, and the answer may exist out there in an archive somewhere, but I am unsure where to go to look for any archives. Any information regarding this matter would be greatly appreciated.
