To send a message to a list use the address (where list-name is the name of the list). If you are a member of the list then, with most lists, your message will be sent directly to the list members. If a list is configured to moderate postings from members of the list your message may be held for consideration by the list manager/moderator, so there will be a delay before your message is sent. If you are trying to send a message to a list of which you are not a member then, by default, your message will be held for moderation. Some lists may be configured to automatically reject all non-member postings.

Message archives

A mailing list may be configured so that messages posted to it are automatically archived. When you join a mailing list you should check to see if there is an archive of previous postings. By reading previous messages you could avoid raising issues that have already been dealt with by the list. To check a list's archives visit the List Home page and click the Archive link. Note that by default lists are not archived.
