Understand a generated guest email address

For GiveCampus accounts and administrator access.

A guest checkout can create an internal guest user with an address shaped guest_<random characters>@givecampus.com when no email is supplied to guest-user creation. This is an application identity, not proof that the donor owns or can read that mailbox. The contribution payer email is a separate field. If that generated address appears where a donor contact address is expected, provide the gift ID and exact screen/export for support to inspect the payer/account mapping; do not replace an institutional contact record based solely on the guest-user address.
