Messaging Security

Messaging Server offers the following sets of security features:

• Protecting Messaging Components in Your Deployment

  With this set of options, you can secure your MTA relays, message stores, Messenger Express mail clients, and multiplexing services. In addition, you’ll learn about third-party spam filter options.

• Planning User Authentication

  These options enable you to determine how your users will authenticate to your mail servers, preventing unauthorized users from gaining access to your system.

• Understanding Security Misconceptions

  Using this set of options, you can perform user authentication and protect the message itself by using authenticated SMTP and certificates for digital signatures, encryption, and Secure Sockets Layer (SSL).
