I can finally say that myred
1) with dedicated IP address need only a wild card [* A myIP] in dns records
2) with shared IP address you need a wild card and an apache handler: ServerAlias *.|DOMAIN|
I experienced personally on my server
The problem remain adding new domain 1)it is impossible wilcard a domain only if it point to another domain; for wilcard a domain I have to install it on the server 2) and if I install the new domain on the server I cannot point it to the other domain ; I can only redirect it and myred dont work with the new domain
