Force smtp authentication for sending mail to own zimbra domain
Posted: Sat Jan 30, 2016 4:26 am
Hello,
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.com to send to my domain you cannot
but if you know an existent address inside mydomain.com you are able to send mail inside mydomain.com with no authentication.
I would like to solve this and ask for authentication in this case too.
Any help appreciated!
Thanks
