The concept of a list server, or mail server, is that several people subscribe to this service, and then when someone has something to say to the group, they simply send the message to a central site, which distributes the message to all members. The sender does not know, or need to know, who the people are.
People can subscribe and unsubscribe whenever they wish.
In order to send to the list, you must be a member of the list. To allow quick downloading of messages, and to prevent mail viruses, the maximum size of messages has been set to 8000 bytes. This prevents Word Documents, executable programs, and large graphics from being passed on the list. This list server contains several mailing lists for different areas related to Environment Canada's CanWarn Project. Environment Canada has graciously permitted this computer system to reside in one of their buildings, but is not responsible for the content of this website nor the list server.
