>> Domain-mapping and multi-domain

Sorry to back with This But again a big problem I dont understand
Situation : I retry to config domain mapping and multi-domain and I met the red problem again with DNS
1. all sites added in multi-domain are green
2. they all got a wildcard *.domain.com
3. they all config with the same IP number
4. they all have a webspace
Do you see where can come the problem ?
I let grant access Open

Thank you
