hello
i used plesk before and for a security reason i migrate to cpanel but i think problem exists.
let me to explain.
my co-workers sets all emails on outlooks and thunderbirds at work. sometimes archly they go to for example thunderbird and changed the email address in setting and send email to others as CEO and finally everyones gets email.
how can i configure exim for block this emails and do not send any non-available addresses or not authenticated users?
