.... well finally I changed my machine completely ispconfig3, but i have a little problems with some configurations, for example in my old machine i accept the alias from the old mail server, for example i put in the /etc/aliases lines likes this :
and them put the command newaliases and ready !
the email that was the old mailserver was redirected to new mailserver ....
i can't do that, i modified the transport_map file from old mail server with the new ip adress of my new mail server but i can't remember what to write and where to write, the access to the old mail server.
some ideas ??? or suggestions ???
