E-Mail Configuration: Internet Link via UUCP on another System

Email configuration tips for an HP3000 which accesses the Internet (or any wide area network) via another system which uses the dial-up UUCP protocol.

This would typically be a Unix host configured with sendmail (or a similar) e-mail package configured to relay mail.

Special configuration options include:

• Your HP3000 should NOT be configured with a default gateway in NMMGR.
• Your HP3000 should not be configured to point to a (DNS) nameserver.
• You must configure a "trusted gateway" in NetMaint. (Designating the relay/UUCP system as your trusted gateway.)
• You should ensure that your Internet Service Provider configure DNS "MX" (mail exchanger) records such that the ISP's machine will pass all mail to the UUCP relay host on their end, and on to the UUCP host on your end.

Note that while mail will be sent to the UUCP host from the 3000 immediately, the UUCP host schedules how often it passes on outbound mail and accepts incoming mail from the Internet (or whatever wide area network the relay is connected to). Also note that since the HP3000 has no access to DNS to verify hostnames when users enter mail recipients, incorrectly spelled or mistyped addresses will be returned by the relay host only after they have been routed to a remote system with DNS access, thus delaying the return of incorrectly addressed messages.
