The glide.user.trusted_domain property specifies the email domains from which the system allows inbound mail. When the system attempts to receive an email, it impersonates the Guest user. The Guest user email address, which is firstname.lastname@example.org by default, will not match one of the trusted domains. However, if there is no Guest user, the system impersonates a user that has no Email specified. This enables the system to receive the email from the untrusted domain.
Enter a value in the Email field for every user in the system.
