Roundcube installation and a domain created with ISPConfig3

[till]

You need a DNS A-record for mail.domain.com pointing to the IP address of the server. A record for just domain.com is not enough. You do not need any redirect as you added a vhost for this subdomain, if you added a redirect, then delete it.

Yes sorry, I've already setup a DNS A record for mail.domain.com.
So at the end I've 2 DNS A records:
domain.com -> 123.456.789.012
mail.domain.com -> 123.456.789.012

You do not need any redirect as you added a vhost for this subdomain, if you added a redirect, then delete it.

That's the point. I want now use the ISPConfig to manage domains, so I've cancel from 000-default apache file the lines for that domain...
Anyway even like that it's not working.
If I restart Apache, I've this warning message:

Restarting web server: apache2[Tue May 25 15:27:47 2010] [warn] NameVirtualHost 123.456.789.012:443 has no VirtualHosts
 ... waiting .[Tue May 25 15:27:49 2010] [warn] NameVirtualHost 123.456.789.012:443 has no VirtualHosts

You said that you created some kind of redirect. Please delete this redirect. Instead of a redirect, create a new website and enter mail.domain.com in the "domain" field of this website.

The point is that I want to redirect who is going to www.domain.com to www.anotherdomain.com, but I want that mail.domain.com is going to the roundcube page...

domain.com and www.domian com are different (sub)domains, they have nothing to do with mail.domain.com. Just create a new website for mail.domain.com and make sure that you have nowhere a redirect for mail.domain.com pointing to another domain.

Ok so I was making confusion... I was thinking that mail.domain.com was a subdomain of domain.com.

Anyway now I've created another domain: mail.domain.com and copied in the folder /var/www/mail.seatel4004.com/web the roundcube files.
Now I can see the roundcube page, but I've a database error.

I tried to use the same database that was using before.
I tried also to create a database with ISPConfig (c0roundcube). I gave to it the privileges:

 GRANT ALL PRIVILEGES ON c0roundcube.* TO roundcube@localhost
    IDENTIFIED BY 'password';

and of course in /var/www/mail.domain.com/web/config/db.inc.php I've put the right user and password.

Well, I still have as error DATABASE ERROR: CONNECTION FAILED!

Am I wrong in something?

Thanks
