Some use cases, like receive-only MTAs, need domain users for receiving emails, but have no real need for passwords since they will never use submission. Today, that is not supported, and those use-cases require the administrator to come up with a password unnecessarily, adding complexity and possibly risk. This patch implements "receive-only users", which don't have a valid password, thus exist for the purposes of delivering mail, but always fail authentication. See https://github.com/albertito/chasquid/issues/44 for more details and rationale. Thanks to xavierg who suggested this feature on IRC.
