[Evolution] Setting Alias Email

[luigi <luigi votta alice it>]

Good day,
I would set in Evolution an email alias, as obtained from fedora.
I've created a new account with the following settings:
E-mail: my_name fedoraproject org
In Mail Server: None
Out Mail Server: That of my internet provider

I cannot send mails to the alias, they get lost, with no response.

If I use a web mail all it's ok.

What can I do, or it's a provider problem?

Thank you
