With Sendmail maybe, but there are a number of SMTP servers that the same server is both used for local and remote receiving into the mail server. The server has a second imploementation for sending outside the server but both the remote servers and local mail clients are connecting via the same server daemon. The server core works to determine whether the mail from the local mail clients are delivered to local addresses to sent onward. > by not allowing it to listen except on the localhost.
