Setting Up E-Mail Service

With DNS correctly configured (on your server or somewhere else), you can set up your e-mail server. Here’s what you do:

1. Launch the Server app from the Dock and select Mail in the sidebar.

2. Check the host name next to Provide Mail For. If you want to change it, click the Edit button and type a new DNS name.

The mail server host name must be resolvable to an IP address with both forward and reverse DNS entries. If you change this host name, you may have to update the DNS MX record (described in the preceding section).

3. In the Mail pane (shown in Figure 13-5), click the switch to the On position.

4. If you’re using an Internet service provider to relay mail to the Internet, do the following:

a. Select the Relay Outgoing Mail through ISP check box.

The relay server could be a server in your own organization. A new dialog appears, as shown in Figure 13-6.

b. Enter an IP address or a DNS name for the relay server.

c. If your ISP requires authentication for its SMTP relay, enter a username and password.

d. Click OK.
