Topic: limit users to send mails to internet
i would like to know if the option enable/diable SMTP work just on authentication, but the protocol is available for the user.
I need to configure that some users can send email only to local users and not to internet .
another question more "naif" : Is it possibile to manage more granular filter for example , certain users cannot send email to some domains and/or recieve from any domain ? All from pro admin .
