I am trying to set a mail server with this tutorial and it worked just great for me. There is although one thing that I am trying and I can't get it to work.
The virtual domain that I have configured on my server is registered at my ISP and I have some email adresses registered at the ISP on this domain. What I want to have on my server is some other email accounts with the same domain name and keep my old accounts on the ISP server, and I want them to be able to send emails to each other semlessly.
I will give an example :
on my ISP server I have these accounts : firstname.lastname@example.org
On my local server I want to have the same domain mydomain.com as a virtual domain and create user3 and email@example.com
and I want to be able to send from these local accounts to the external accounts.
When I try to send something to an external account the server tells me :Recipient address rejected: User unknown in virtual mailbox table which is quite normal as it cannot find this address on my server but is there a way to make him go external through my relayhost when it doesn't find a registered account
Thanks to all
