The "domain limit" requires that people register with email addresses in the specified domain(s). For example, if you would like all students to use school email addresses, enter your school email domain, without the "@" symbol, here. Enter variations using commas and no spaces, such as "school.edu,mail.school.edu,students.school.edu."
A benefit of using the domain limit is that, if you have set schedule limits and/or are using a no-show policy, students cannot simply create extra accounts in order to make more appointments. For example, if Jane Doe at University X already had an account under "firstname.lastname@example.org", and she had already reached your weekly appointment limit, she might register a personal email account, "email@example.com", and then log in and make an additional appointment. With the domain limit set to require "ux.edu" email addresses, Jane would not be able to register with that "personal-email.com" address.
If you would like to validate university email addresses without using LDAP or SSO, combine the domain limit with registration confirmation by email (also in Global System Settings). Using both together ensures that students are using valid, working school email addresses to register.
Occasionally, and not at all frequently, customers see spam registrations. These are entirely harmless, as even a human being logging in under such an email address would only be able to make an appointment as a non-administrator, but seeing spam email addresses can be annoying. One way to prevent spam bots from registering is to add CAPTCHA. Another way to prevent spam registrations without requiring students to respond to a CAPTCHA prompt is to add a domain limit.
