Fully Distributed (Standalone System) Topography
When using a Fully Distributed electronic mail topography each
computer is a standalone machine (with regard to electronic mail). Each
machine is effectively its own workgroup and is configured just like the
hub computer in a “Central Mail Hub” topography e-mail network.
Configuring each System The procedure for configuring each system
in a “Fully Distributed” topography is:
Step 1. Edit the file /etc/rc.config.d/mailservs:
a. Set the environment variable SENDMAIL_SERVER to 1 to indicate that
this computer will run the sendmail daemon to receive mail:
SENDMAIL_SERVER=1
b. Do not set the environment variable SENDMAIL_SERVER_NAME which
would indicate that another computer serves this one:
SENDMAIL_SERVER_NAME=
c. (Optionally) Set the environment variable SENDMAIL_FREEZE to 1 to
indicate that the sendmail configuration file is to be frozen. With
older computers, and in certain other circumstances, a frozen
configuration file can speed up sendmail’s performance by reducing
the time it needs to parse its configuration file.
SENDMAIL_FREEZE=1
Step 2. Reboot the computer to start up and properly configure the sendmail
daemon.
