Response:

Customer Contact

Response:

Desc:   email outside the RISC to the Internet is not working.
        customer needs info on how to setup the sendmail.cf file.

Act:    The Commo web page contains info...

Q: I want all external mail routed through my mail "firewall".

A: You will need to add a line to your /etc/sendmail.cf file specifying
   the name of this "relay" machine. The line you need to add is :

   DRRelayHostName

   By default, this line is commented out. You can uncomment it and
   change "RelayHostName" to the name of your firewall machine.

   PLEASE NOTE: On AIX 3.2 and AIX 4.1 after making any changes to the
   sendmail.cf file, you must run the commands 'sendmail -bz' and
   'refresh  -s sendmail' to recompile the configuration file and force
   the sendmail daemon to reread the configuration file.  The command
   'sendmail -bz' is not supported on AIX 4.2.

        we changed the DRRelayhost to:  DRfirewall.delta.com
        which is the firewall system and should handle all
        incoming and outgoing mail for them.

        to test, we run:

                mail -v nick@skymail.com
                which sends a note with verification afterwards...
        the info was similar to an email sent from IBM out to the internet...
        $ mail -v p.clifton@ieee.org 
clifton... setsender: uid/gid = 260/1
