I know there are probably several ways to do this, ie running a name server etc etc, but I am looking for the easiest and possibly the quickest way to do this:

# I have 1 static IP address.
# 4 domain names which point to the 1 IP address.
# I intend on running 4 websites from the one machine(already setup with Virtual Hosting)
# I need to have several (3 minumum) pop3 accounts for each domain name.

Any help and advise would be greatly appreciated.

I am running Slackware 9.1 for this particular project...
I had initially intended on obtaining a block of IP addresses but have decided for cost reasons etc to try and do it this way.

set the A record for each domain to point to the 1 domain.

namebased virtual hosting - like described in detail at http://httpd.apache.org/docs-2.0/vhosts/name-based.html is the goal

go the web side of things pretty easily, it is the mail that I am not too sure about.

Any help would be greatly appreciated...

Thanks in advance!
