Lists with low volume will have messages sent out as soon as they are received by the listserver. High volume lists may have delayed mailing until the system load is low enough so that the mailing would not adversely effect users. List archives will be maintained on disk and subject to normal backup procedures. List names should be reasonably short as people will have to type them on occasion. They cannot duplicate existing listname or username in use on the server machine.
Names are case-insensitive.
Lists are private by default and all subscription requests must be confirmed by the list owner. This reduces the effect of list spammers. The maintenance password is used to authenticate e-mail between the list owner and listserver.
