Notes/Domino 4 and 5 Forum

Hello everybody,

That's my 1st message.

So i 've got a notes domain and a internet domain ("society1.com")

We 'll buy a new society which don't have any server mail.
So i have to create a second internet domain like society2.com.

=> In a one domain, is it possible to have 2 or more internet Domain?
For example: user1@society1.com and user2@society2.com

how can we install that?

-may i change the field "email adress" in each person document?
or there exist another methods with the document "global domain"?

thank you very much!!

See you later.
