The List Posting Address
Email Address: Listname@
Purpose: The address for sending mail to all the members of a mailing list. For example, if your list is called "jazztalk" and your server is named "clio.lyris.net", then you can submit postings to your list by sending email to jazztalk@clio.lyris.net.
If you'd like to send to a subset, the address is the listname, followed by a period, the subset name, and the name of the server. For example, if your list is called "jazztalk", your subset name is "clubs", and your server is named "clio.lyris.net", you can submit postings to your list by sending email to jazztalk.clubs@clio.lyris.net.
