Introducing Sendmail for MPE/iX 7.5

By Mark Bixby, Commercial Systems Division

Previously available as unsupported freeware, Sendmail is now bundled into MPE/iX 7.5 FOS 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 7.5 Release.

• 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 HP 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” for more

detail.

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

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

Issues” for more detail.

Support

Sendmail 8.12.1 for MPE/iX is supported through the HP Response Center as part of MPE/iX FOS support.
