Setting Up a Mail Proxy Server

A Mail proxy server provides secure SMTP mail services for incoming and outgoing mail. It can also be used to hide internal domain names and mail hosts for scanning incoming mail. You can use the Mail proxy between the existing intranet mail server and the Internet, or directly between the intranet and the Internet without an intranet mail server.

To set up a Mail proxy server:

  1. In NetWare Administrator, select the Novell BorderManager 3.7 Setup page for the server.

    2.

  2. From the Application Proxy tab, check the Mail Proxy check box.

    3.

  3. Click Details or double-click the Mail Proxy service.

    4.

  4. Enter values for the following Mail proxy parameters:

    • Spool Directory---The directory in which the mail files are temporarily stored.

      This must be an absolute path on the server, including the volume name, for example, SYS:\ETC\PROXY\SPOOL.

      •

    • Spool Directory Max Size---The maximum size (in MB) of the mail spool directory.

    • Max Mail Size---The maximum size (in MB) of a mail item.

    • Failed Mail Retry Interval---The maximum number of minutes before the next attempt by the Mail proxy to forward undeliverable mail.

    • Failed Mail Retry Count---The maximum number of times the Mail proxy attempts to forward undeliverable mail.

    • Primary Mail Domain Name---(Optional) The domain name that is used to substitute the From address in an e-mail message. This name replaces the internal domain name in outbound mail headers and hides the internal network architecture. If this parameter is unspecified, the local DNS domain name is used as the primary mail domain name. If the local DNS domain name is not configured as well, the From address remains as is.

    • Internal Mail Server Name---The Mail eXchange (DNS MX record) name or internal mail domain name of the mail server on the internal network.

    • POP3 Mail Server Name---The name or IP address of the server running the Post Office Protocol 3 (POP3) software.
