Host file

[Jon L. Miller]

So If I have a file such as this:
/etc/mail/access
    192.168.1.1     RELAY
    10.0.0.6        RELAY
    gooddomain.net  RELAY
    baddomain.net   550 Mail from your domain is denied
    192.168.1.10    550 Internet mail may not be sent from this host.
If I wanted to set the RELAY to allow mail from 192.168.2.2, this would
allow email to relay from the 192.168.2.2 on this mail server is that
correct? Do I have to run any other program to get this information in the
system?

Not if you are the only one that will be using it.  Why register something
in a global database if you don't want the world to know it's there?

That's a mail server configuration problem.
The mail server needs to be told, that it can receive mail from your home
computers and send them on (relay them) to the outside world.

By default all mailservers are now configured to not relay for anyone,
because otherwise joe spammer in portugal could use your mailserver to
send his SPAM.

If you're using smail, you can enable relaying for your network by
configuring the line:

smtp_remote_allow=192.168.1.*

where 192.168.1.* is the IP range for your network.

If you're using postfix, set up the lines:

mynetworks = 192.168.1.0/24
smtpd_recipient_restrictions = permit_mynetworks

to match your domain.
