System Requirements and Patches

• MPE/iX 7.5

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

• Sendmail uses the POSIX time functions in order to timestamp messages, and these functions depend on the TZ environment variable being set properly. The best place to set TZ is in your system logon UDC, i.e., SETVAR TZ "PST8PDT" (Pacific Time Zone example). For further information about TZ, please see "man timezone" or /SYS/LIB/TZTAB.

• Syslog/iX must be configured and running so that Sendmail can log warnings, errors, and message traffic data. Note that some third-party spooling packages come with their own embedded syslog daemon that will prevent you from running Syslog/iX; if you are using such a spooling package, you will have to use the embedded syslog daemon to capture Sendmail logging events. Syslog/iX is documented in the Configuring and Managing MPE/iX Internet Services manual. If you will be using the FOS syslog daemon for the first time because of Sendmail, please ensure the SYSLOG account file ownerships are correct by performing the following steps:

  1. :HELLO MANAGER.SYS

  2. :XEQ CHOWN.HPBIN.SYS '-R MGR.SYSLOG:SYSLOG /SYSLOG/PUB'

• 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" below 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" below for more detail.
