Rather than creating and maintaining a list of e-mail addresses for a group you mail frequently, use a mailing list service to create the list and allow users to maintain which e-mail address messages are sent to.
We used to offer a Sympa Listserve for just this purpose, but we now must point you to the UIT Sympa or Exchange mailing lists: https://uofu.service-now.com/cf/kb_view.do?sysparm_article=KB0000547 and https://www.lists.utah.edu/
Sympa or Exchange? https://uofu.service-now.com/cf/kb_view.do?sysparm_article=KB0001129
We will continue to support existing lists via our Sympa server until they can be merged to UITs servers by June 30, 2017.
See https://sympa.eng.utah.edu/sympa. You should log in with the e-mail address you’ll be using to manage the list as your username. Use the Help tab for instructions, but creating a list is easy on the ‘Create List’ tab. Log back in once created to manage how messages are sent, who can see the archives, etc.
