Change default email to Roundcube

[iconus]

Thanks for the help but it isn't working. Would a created subdomain that is mail.mydomain,com interfere with anything should I delete it? It's still isn't working though, here is what I have now, can you check and see if there is anything wrong with it?

<VirtualHost *>
ServerName webmail.{domainname}
ServerAlias mail.{domainname}
ServerAlias email.{domainname}

DocumentRoot {ehcpdir}/webmail2;/usr/share/roundcube

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%v:%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
CustomLog {homedir}/logs/access_log combined
CustomLog /var/log/apache_common_access_log vhost_combined

php_admin_value open_basedir {ehcpdir}/webmail2;/usr/share/roundcube
</VirtualHost>

Thanks for your help
