Hello,
Could You give me general advice for configuring mail-enable as mailserver for internal network.
Goal is users within mail-enable server should be able to send - receive only inside this server and created account - cannot send anywhere else to and from internet for example to xxx@gmail.com only mailbox@domain.thatnotexist.
I was checking out SMTP outbound tab on configure but I can't really what option might restrict access for my case.
Regards
