I'm sorry but for privacy reasons I can't post here the content of /etc/postfix/local-host-names and /etc/postfix/virtusertable
Maybe if you tell me what I have to look for...

This is the output for

postconf -n:

Of course there is an account for on the receiving mail server but, as I can understand, postfix just looks inside without trying to send the email. It thinks to be the mailserver. It looks for the user and cannot find it. So I, as a postmaster, receive the email of not delivery report with "user unknow" as error.

Making a practical example:

this is the shop address:
shop owner email address:
client1 email address (generic):
clent2 email address (same company):

Case 1:
Someone with a generic email address (client1) registers himself on the OSCommerce shop.
When he purchases something there are two emails sent. One email is sent to the shop owner and the other to the client.
Mail to the owner: OK (since I've added the user on ISPConfig - see previous post)
Mail to client1: OK

Case 2:
Someone from the same shop's company, or someone else for whom i'm hosting the website on the same server, purchases anything this is what happens:

Mail to owner: OK
Mail to client2: postmaster receives the NDR (user unknow)

I hope that the picture of the situation is clearer now.
This is really odd and for me, not a good linux user , it is very difficult to fix something like that.
