by Mark Bixby, Commercial Systems Division

Previously available as unsupported freeware, Sendmail is now available for MPE/iX 7.0 via patch

SMLGDT8A as a fully supported product which allows you to send and receive SMTP-based e-mail. The

initial A.01.00 release of Sendmail for MPE/iX is based on the 8.12.1 Internet open source version from

sendmail.org.

System Requirements and Patches

Sendmail has the following prerequisites:

•MPE/iX 7.0

• HP highly recommends installing the latest NSTxxxxx network transport patch.

• Syslog/iX configured and running so that Sendmail can log warnings, errors, and message traffic data.

Syslog/iX is documented in the Configuring and Managing MPE/iX Internet Services manual.

• Your e3000 must be configured to use one or more DNS servers, and must have the correct entries in the

DNS database corresponding to the configured hostname in :NMMGR. See “DNS Issues” below for more

detail.

• Any network firewalls, routers, or switches that your e3000 communicates with must be configured to

allow your e3000 to send and receive packets on port 25 (SMTP) and port 53 (DNS). See “Firewall Issues”

below for more detail.
