I have a head office where my SME server connecting with ADSl , the mail for the internal network is working fine .
The branches on different locations have the same domain name and works with the ISP's mail server pop& SMTP.
When a user sends mail from my local lan to the SME server and the user does not exist , it should forward to the ISP server for the user to pop from external.
E.G user1@mydomain send to user2@mydomain. User2 is not a user on SME server but has same domain name.
User1 get mail from SME server ( the SME server gets it from ISP) , and user2 get mail dirct from ISP. They are in different locations.
Is this possible to setup without the "unknown user" message ?
I really would apreciate help.
Thanks
