Hi thanks for your reply and sorry for may late response..
For this website there are no accounts starting with contact of contacts..
If there where accounts it would be logical the aliasses should fail, but that is the strange thing about these aliasses.. Also no error message is given.. they are just not added. When I add testing123 it is saved, so it is also no limit of aliasses..
