6.6 Setting per-domain SMTP parameters

Using System Manager, you can define configuration settings for each external SMTP domain to which your system will connect. These per-domain configuration parameters include settings such as whether to use MIME or UUEncode, whether to send rich-text format, whether to word wrap lines, whether to send out-of-office messages, and many other options. All SMTP virtual servers and SMTP Connectors will use these settings. You can set per-domain SMTP parameters using the following procedure:

1. Start the System Manager from the Windows 2000 Start menu by selecting Programs   Microsoft Exchange   System Manager.

2. Expand the Global Settings section.

3. Expand the Internet Message Formats section.

4. To modify the default parameters, double-click the Default entry to display the Default Properties window. To modify the parameters for a specific domain, double-click the entry for that domain. To add settings for a new domain, right-click on Internet Message formats and select New   Domain.

5. In the Name field, enter a name for this set of per-domain parameters (Figure 6.4).

   
   Figure 6.4: The General tab

6. In the SMTP domain field, enter the domain to which these parameters apply.

7. Select the Message Format tab to specify the message formats that will be used when communicating with this domain (Figure 6.5).

8. Select either MIME or UUEncode as the message encoding type that will be used for sending messages. Both UUEncoding and MIME are methods of encoding binary data so that the data can be sent using the 7-bit ASCII character set required by SMTP.

   MIME (Multipurpose Internet Mail Extensions) is defined in RFC 1521 and extends SMTPs capabilities to send binary data. Most, but not all, SMTP servers support MIME. The BinHex check box is for exchanging files with Macintosh users.

9. You can also select the character sets to be used. US ASCII is the default.

10. Select the Advanced tab (Figure 6.6).

11. Select when to send Exchange rich-text format. The options are:

    • Always use . Always send rich-text messages to recipients in this domain.

    • Never use . Never send rich-text messages.

    • Determined by individual user settings . Send rich-text only when the recipient is configured to receive it.

12. Select the Out of office responses check box to allow automatically generated out of office messages to be sent to this domain. If the specified domain is the Internet, and if your users are listed on large external distribution lists such as those maintained by various Internet newsgroups, it is best to disable out of office messages to the Internet so that these messages are not sent to the external list.

13. Select the Automatic replies check box to allow automatic replies to be sent to this domain. As with the out-of-office responses, it is best to disable this option if the specified domain is the Internet.

14. Select the Automatic forward check box to allow messages to be automatically forwarded to this domain.

15. Select the Allow delivery reports check box to allow delivery reports to be sent to this domain.

16. Select the Allow non-delivery reports check box to allow non-delivery reports to be sent to this domain.

17. The SMTP virtual servers can be configured to include the senders display name (usually the senders full name) in addition to the senders e-mail address. Select the Preserve senders display name on message check box to include the senders display name.

18. Select the Details tab.

19. Use the Administrative note field on the Details tab to enter additional information about the per-domain properties.
