A new keyword has been added in version 1.5j, as per a suggestion from Alan Crosswell: Default-options= opt1,opt2,... The default list distribution options assigned to a new user upon completion of a SUBSCRIBE or ADD command are automatically altered as though a "SET listname opt1 opt2..." command had been issued immediately after the ADD/SUBSCRIBE. The user is informed about this special set of options in the standard ADD mailfile (mailform ':ADD1') for an ADD command, or by message for a SUBSCRIBE command. Eric
