Everything I have found on this error points to Azure or O365 but I am dealing with neither of those. What admin-defined policy do I need to change?

Not allowing email verified users to be added due to an admin-defined policy

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.
