Automatically add bcc or cc when my staff send email from their email account

We are using cyberpanel latest version. We want to know that is there any way to add bcc or cc automatically to some of our staff email accounts so that when they send emails to someone, the server will send a copy of the email to the owner/administrator email address?

Yes you can create a fwd of the outbound with this command:

postconf -e always_bcc=your@email

This will fwd all outgoing emails to the desire address.
