NNTP Mailbox and Custom Recipient Configuration

You can specify whether an NNTP client can use a mailbox or a custom recipient to be authenticated to connect to Microsoft Exchange Server. Disabling NNTP access on a mailbox or custom recipient means that an NNTP client cannot connect to the server using that mailbox or custom recipient's credentials. To provide authenticated access to a user who has a mailbox in your Microsoft Exchange Server organization, NNTP must be enabled at the mailbox and at the server. To provide authenticated access to a user without a mailbox, create a custom recipient for the user with an associated Windows NT account. The NNTP client must provide this account information when connecting to Microsoft Exchange Server.

Note   If you disable the NNTP protocol on the server object, NNTP support is also disabled for individual mailboxes. For NNTP to be enabled on a mailbox, it must be enabled on the server and mailbox.

Getting to the Protocols property page

1. In the Administrator window, choose Recipients.
2. Double-click the mailbox or custom recipient you want to configure.
3. Select the Protocols tab.

Enabling NNTP for a Mailbox or Custom Recipient

Use the Protocols property page to enable NNTP for individual mailboxes or custom recipients.

1. Select the Protocols tab.
2. Select NNTP (News), and then choose Settings.
3. Select the Enable NNTP for this recipient check box.

Specifying NNTP Settings for Message Encoding

If NNTP is enabled on a mailbox or custom recipient, you can use default settings for the message format. Alternatively, you can customize the settings for individual mailboxes or custom recipients. You can specify how text and attachments are encoded and the character set that your recipient uses.

The settings in the Message Format property page determine the format that Microsoft Exchange Server messages are converted to when they are retrieved by an NNTP client. Messages sent by an Internet user are not converted. Instead they are retrieved by the NNTP client in the format that the message was originally composed in.

1. Select the Protocols tab.
2. Select NNTP (Mail), and then choose Settings.
3. Select options for message content defaults and message encoding. To use message format defaults that you set at the server level, select the Use protocol defaults check box.

For information about these options, see "Message Format Properties" earlier in this chapter.
