Sample sendmail.cf file for the 3B1/7300

Sat Feb 25 12:52:21 AEST 1989

Here is a sample sendmail.cf file for use with the recently posted sendmail
program.  This file makes the following assumptions:

1. The name of your site is "Galaxia".  If not, change the "Dw" line.

2. Your domain name is "Newport.RI.US". Change the "DD" line.

3. You are using regular style uucp with an L.sys file.  Change the "FU" line
if you are using HDB uucp.

4. Local mail delivery is done using the "lmail" program.  Change the "Mlocal"
line if you have a different local delivery program.

5. Non-local delivery is done using the "smail" program.  Change the "Muux" line
if you do not have smail or if you are using a different program.

6. Read through the entire file and check to see if anything else looks out
of place for your system.  It is helpful to read the sendmail documentation
before looking a this file.
