Preventing Spams and Relays

The smtpd package is a useful mail daemon for stopping spam, thereby saving money and resources.
Summary

The Internet is no longer the “friendly global village” we once thought it was. Living among the netizens are unscrupulous individuals and even companies that take advantage of the openness of the Internet for their own benefit while making others bear the cost. We must take preventive measures against these attacks if we want to avoid becoming victims. Proper policy on the e-mail server will help to ensure this. With smtpd in place, you will have more control of your e-mail server.
