  1. In the console tree, navigate to Server Configuration > Client Access.
  2. In the work pane, click the POP3 and IMAP4 tab.
  3. Select POP3 and then, in the action pane, under POP3, click Properties.
  4. On the POP3 Properties page, click the Authentication tab.
  5. Under Logon Method, select one of the following:
    1. Plain text logon (Basic authentication)   No TLS connection is required for the client to authenticate to the server.
    2. Plain text authentication logon (Integrated Windows authentication)   No TLS connection is required for the client to authenticate to the server.
    3. Secure logon   A TLS connection is required for the client to authenticate to the server.
  6. Click Apply, and then click OK to save your changes.

Use the Shell to configure authentication for POP3

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "POP3 and IMAP4" entry in the Client Access Permissions topic.

This example allows Basic authentication on an unsecured port if you won't be using TLS encryption.

Set-PopSettings -LoginType PlainTextLogin

This example restricts Basic authentication to use only secured ports if you won't be using TLS encryption.

Set-PopSettings -LoginType PlainTextAuthentication

This example allows authentication after you use TLS encryption.

Set-PopSettings -LoginType SecureLogin
