unhosted domain pointed at server leads to first account not /usr/local/apache/htdocs

[boatdesign]

New whm/cpanel server has one weird thing:
if someone points a domain at the main namebased hosting IP and there is no account setup for it, it loads the first-created namebased site (i.e. it loads /home/account1/www/)

So if you remove an account and they're doing their own dns, now that domain shows another account. It should show the default page at /usr/local/apache/htdocs/index.html

In the httpd.conf whm builds this:
<VirtualHost *>
ServerName hostname.mydomain.com
DocumentRoot /usr/local/apache/htdocs
ServerAdmin email removed
</VirtualHost>

If I change it to
<VirtualHost main.server.ip.number:80>
ServerName hostname.mydomain.com
DocumentRoot /usr/local/apache/htdocs
ServerAdmin email removed
</VirtualHost>
it works as I expect it should (if a domain is pointed at the server's namebased IP and it's not created yet or deleted, it shows the default server page not another account.)

In the old days I would edit the httpd.conf to change something like this, but now with easyapache I need some direction on how to fix this so it doesn't get unchanged the next time apache is built. Many thanks in advance.

You might want to look over the docs.

Thanks Infopro.

Searching the docs, it seems simply editing /var/cpanel/templates/apache1/main.default makes it easy to make the change stick.

Edit: something else seems to be in play here -- maybe a bad apache build last time even though I did not see any errors.

It struck me as odd that the way it worked and the way the comment tag implied it should work were in conflict, so I tried backing it out and rebuilding a third time and now it works as designed and in practice I think.

In the generated httpd.conf I now have

# DO NOT EDIT. AUTOMATICALLY GENERATED. IF YOU NEED TO MAKE A CHANGE PLEASE USE THE INCLUDE FILES.
NameVirtualHost main-server-ip:80
NameVirtualHost *
# DO NOT EDIT. AUTOMATICALLY GENERATED. IF YOU NEED TO MAKE A CHANGE PLEASE USE THE INCLUDE FILES.

<VirtualHost main-server-ip:80>
ServerName hostname.servername.com
DocumentRoot /usr/local/apache/htdocs
ServerAdmin removed
</VirtualHost>


# Default vhost for unbound IPs

<VirtualHost *>
ServerName hostname.serverdomain.com
DocumentRoot /usr/local/apache/htdocs
ServerAdmin removed
</VirtualHost>

The top section was not there before... weird.
