Distribution list basics
A distribution list, also known as a mailing list, is a collection of email addresses that allows you to email multiple people at one time. A distribution list can contain a few addresses, or many.
All email systems at Indiana University provide ways to create, manage, and send to distribution lists, but the available commands, options, and capacities will vary on each system; see Sending email to a large group Lists housed on specific systems are unavailable for shared use on other systems.
LISTSERV is a system-independent distribution list management system available to all email systems at IU. With LISTSERV, you can create a distribution list and configure it to allow others to send messages to your list, regardless of which email systems they use. See LISTSERV and other mailing lists.
