To avoid a personal e-mail account from being used to send spam, there is a limit on the number of recipients that can be added to one e-mail on your Exchange account.
Obviously, there are many times when you may want to send to more than this number, or a time when you would like people to subscribe to a newsletter. Additionally, many departments like the ability to send to one e-mail address, knowing that everyone in that department will then receive the message. For this reason, the IT department offers Sympa - the mailing list system.
Sympa mailing lists have an e-mail address that ends with @lists.unr.edu. They are highly configurable - allowing you to modify who can send and receive certain messages.
