This allows listing out authorization identities. If the incoming client is authorized to act as one of the listed `relay_from_authz` authorization identities, then the incoming session will be added to the relay_from CIDR for the scope of that connected session, and the result is that they will be allowed to relay from the associated domain. This is useful if you want to give a tenant SMTP auth credentials but only want to allow them to send from the domain(s) that they are permitted to send as/from.
