Force smtp authentication for sending mail to own zimbra domain
i searched for two days (and two nights ;-)) but i could not solve this problem.
I configured mydomain.com
My smtp is not an open relay and it asks for authentication to send mail outside.
If you try to telnet the server and try to use a non existent address @mydomain.comÃ‚Â to send to my domain you cannot
but if you know an existent address inside mydomain.comÃ‚Â you are able to send mail inside mydomain.comÃ‚Â with no authentication.
I would like to solve this and ask for authentication in this case too.
Any help appreciated!
