Thanks very much for that suggestion.
I've looked at KMail showing all headers,
and there are a couple of IP addresses which could be the correct ones:
-----------------------------------
Received: from smtp-out01.alice.it (85.33.2.12)
...
Received: from althea.gayleard.com ([95.234.133.98]) by 
FBCMCL01B05.fbc.local with Microsoft SMTPSVC(6.0.3790.3959);
-----------------------------------
I'll see if I can check if the second address is OK.
I don't seem able to ping it.
