OK, that is what the last part of my posting refers to - I am quoting it here.

Now, for one web server - apache - to server more than one domain,
you have to enable virtual hosts in apache's config file. Edit
/etc/httpd/conf/httpd.conf, and add the lines - suitably modified for
your use -

<VirtualHost www.somedomain.com>
ServerAdmin somedomain-admin@localhost
DocumentRoot /home/somedomain/public_html
ServerName www.somedomain.com
ErrorLog logs/errors_somedomain.log
TransferLog logs/access_somedomain.log
</VirtualHost>

For every virtual domain that you need to have. Note that these virtual
domains (here, www.somedomain.com) should have valid DNS records - it is
better if your run named on the server as well, with the configuration
you like.

What I wanted to say in my previous mail was, having only one interface
and one IP address for that, it is your job to configure individual
programs to reply to different names. There is no system wide kernel
level configuration for this. I have outlined how to configure your web
server to do this. In a similar way, you will also have to configure
your SMTP server, your DNS server and all other servers to achieve the
desired effect.

Hope I am clear,
