Required Edits
To set up SMTP for your organization, you only need to make a few changes to the
SMTPCONF file. The editing required includes the following:

Change the Class W (Cw) specification (Internet host-name) to your host-name.

Change (DN) to the hostname that you want other hosts to know you as.

Alter the macro A (DA) to add in the ARPANET gateway, if you have one.

Alter the Class A (CA) to your ARPANET gateway, if you have one.

Define your local domain class (CD line).

Define your major UUCP relay host class R (CR line).

Alter the macro R (DR) to the major UUCP relay host name.

Alter the option OC to your SMTP gateway correspondent name.

Alter the option OP to the password for your SMTP gateway correspondent.
Remember that the password is case-sensitive.

Alter the option OA to the system administrator who should receive mail that
cannot be returned or delivered.

Alter the option OT to specify the names of TISERV processes if ones other than
the default $ZCC0 are to be used.
Optionally, you can alter the option OE if a message expiry (expiration) time other than
96 hours is required.
Example of SMTPCONF File Lines
The following text is an example of the SMTP configuration file supplied with the
NonStop TCP/IP software. These lines indicate the changes you must make to the file.

# Enter the internet host-name for your machine here. In
# this example, the host-name is “Expand”. Replace “Expand”
# with your machine name.
Note. If you make changes to the configuration file after the SMTP server is started, you must
restart it before the changes to take effect. Restarting the SMTP server or client does not
cause any loss of messages.
