Enable authentication in your mail client. If you cannot figure out what that is you need to post your email client or perhaps do some reading on google. Email authentication is very basic and should be easy to find in an email client.

When I send an email from one email address to such email address, I get this:

Looks like the domain you are sending to points to a server it's not setup on.
So the domain is not listed as a local domain - it therefore thinks you are trying to use it as an open relay, and it's rejecting it. You need the domain to be added to the list of local domains.
I already authenticate in my emai client but then I get:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was [email protected]'.
