Force smtp authentication for sending mail to own zimbra domain

Postby Bruce999 » 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
