people should receive notification when email created for him from ispconfig 3

in ispconfig 3 control panel (version 3.0.3.1), after add a website site-1.com, create an email (e.g. email4u@site-1.com) under this domain for a person (say myfriend@gmail.com). how to make the system to send an email to this person (myfriend@gmail.com) as well? can the system do it?

when creating an email, under the Mailbox page, there is a "Send copy to" (optional) field, from the ispconfig 3.0.3.1 manual, it says when sending email to email4u@site-1.com, myfriend@gmail.com should receive a copy. i test this functionality, but it doesn't work.

but what i want at the moment is that my friend myfriend@gmail.com will receive a notification when an email email4u@site-1.com is created for him from ispconfig 3 control panel? please help with this!

 

ISPConfig 3 sends a notification to the account you create, but not to any other email account.
