Subject:  Sending mail from AIX to the external Internet
 
Even though it is not possible to establish a direct TCP/IP connection
from an AIX system at Almaden to the external TCP/IP Internet, it is
still possible to send mail from an AIX system to the Internet.  This
requires going through two gateways:
 
    1) The ALMADEN gateway (also known as XAGENT), which converts mail
       from TCP/IP network to VNET.
 
    2) The VNET-INTERNET gateway (also known as the CSNET gateway),
       which sends VNET mail to the external Internet.
 
 
Here are the steps for setting up an AIX system to send and receive
Internet mail:
 
1) You must be registered to use the VNET-INTERNET gateway.  If you are
   not registered, use the External Network Access Registration Form,
   available at the Operations counter (G1-400), to register.
 
2) Make sure that you are registered to use the ALMADEN gateway.  If mail
   that is sent by VM users to "youruserid at ALMADEN" goes to your AIX
   userid, you're set.  If it goes to your VM account, then you need to:
 
      a) Log on to your VM account.
 
      b) Issue the command:
 
             SMSG NET CMD ALMADEN FORWARD ADDALIAS aixuserid aixnode SMTP
 
         Replace "aixuserid" with the AIX userid that you want to send
         mail from, and "aixnode" with the AIX machine name that you want
         to send mail from.  For example, to send mail from
         elmer@fudd.almaden.ibm.com, you would use:
 
             SMSG NET CMD ALMADEN FORWARD ADDALIAS ELMER FUDD SMTP
 
      c) Wait 2 hours for this command to take effect.
 
3) Install a special version of the sendmail configuration file by
   logging in as root on AIX (or doing "su" command) and doing the
   following commands:
 
       cd /usr/adm/sendmail                     <-- If AIX/RT
       cd /usr/lib                              <-- If AIX/6000
       mv sendmail.cf sendmail.cf-orig
       cp /local/lib/sendmail/sendmail.cf .
       sendmail -bz
       ps -ae | grep sendmail
       kill nnnn                (where nnnn is the number in the first
                                 column of the ps -ae response)
       /usr/lib/sendmail -bd -q30m
 
4) Make sure you can send mail to VM users.  Send yourself some mail
   to your VM userid, just to check.  From AIX, you might type:
 
       mail vmuserid@almvmd < /etc/rc
 
   where "vmuserid" is you VM userid.
 
5) Send mail to an Internet address while you are logged onto VM.  Log
   onto VM in one window.  In an AIX window, type something like:
 
       mail xyzzy@berkeley.edu < /etc/rc
 
   This will attempt to send mail to "xyzzy@berkeley.edu".  Within
   two minutes, you should get a message in your VM window indicating
   that the file was received by the CSNET gateway, and "shortly" after
   that (1 minute to 3 days later) you will get a message indicating that
   the mail was actually delivered to the addressee's system.
