Can an address at katergizmo.de receive email?

The domain has mail servers configured, but this does not confirm that a particular mailbox exists or will accept email. Disposable inboxes are temporary, even when they can receive verification emails.

Should I block katergizmo.de at signup?

Send the address to GET /email/{address}, or the domain to GET /domain/{domain}, and reject the signup when disposable is true.
