That's ancient. I strongly suggest that you update, on
security grounds as well as good general practice.

Please use the "return" key occasionally.

Exim has gotten as far as trying to work with the address <root@> and
cannot handle it thanks to the lack of a domain (the part after the '@'.

For example in your address <scrivimi2005-exim@???> the domain is
"yahoo.it".

I expect you have your firewall configured to send mail to "root" and
are expecting Exim to add the domain part of the mail address. Look
at your qualify_domain and primary_hostname main configuration options.
