To send a message to all of the people currently subscribed to the list, send mail to: email@example.com
This is called “sending mail to the list” because you are sending mail to a single address and LISTSERV makes copies for all of the people who have subscribed. This address (firstname.lastname@example.org) is also called the “list address.”
More information on LISTSERV commands can be found in the LISTSERV reference card, which you can retrieve by sending an “INFO REFCARD” command to email@example.com.
