Final answer:
Alumni are not eligible for Gatormail; this service is for current students, faculty, and staff of the University of Florida.
Step-by-step explanation:
The affiliation that is NOT eligible for Gatormail is Alumni. Gatormail is a service provided by the University of Florida for its current students, faculty, and staff. Once students graduate, their account typically undergoes a transition and they are no longer considered current members of the university with access to Gatormail, although they may have access to other alumni services.
