This must be a problem of my installation because I cant send or receive emails from any account I create.
I have Plesk 12 and smarter mail professional 13.1

Is this a residential or commercial Internet account? Who is your Internet provider? Many residential providers completely block port 25, which must be open for MX servers.

if port 25 is shut, you don't get the message that the user does not exist.

probably he was connect via intranet.  You just do not get .. "user does not exist" when there is no mailserver listening at all @ 25. 
But I see there is no problem for him anymore. 
A test on postmaster works now
