This applies to ACES buildings.  This may not be the case for non-College of ACES buildings and is subject to change.

Note: "Listserv" means "mailing list" in this kb article.  An example of a listserv is the aces-bldg-mh@aces.illinois.edu email employees in Mumford Hall receive about building maintenance and announcements.

Certain listservs in the university are auto-filled based on the U of I's HR system.  This is the case for building listservs, such as the one listed above for Mumford.  
To change the listservs an employee is listed under, they will have to go to hr.uillinois.edu/myinfo and edit their office address's mail code.  This will make a change during night hours so they will now receive emails from listservs that are associated with that new mail code.

If you are unsure what your buildings mail code(s) is, go to this link and find your building: https://printing.illinois.edu/campusmailcodes. Some buildings may have more than one mail code.
Note: For Mumford Hall, the mail code is: 710
