You need to look into SMTP AUTH. Google it, study the Exim docs,
whatever it takes. The idea is to require a username/password (which
can be encrypted with TLS if you like), before allowing ANYONE to relay
through your machine. This is the only way I know of to setup remote
mail users (other than direct dial-up customers) without becoming an
open relay.
