Ok I found the way:
1.assign 2 IP addresses to my Windows 2003 server (Ip1 and Ip2)
2.assign main virtual smtp server to listen from Ip1
3.create a 2nd virtual smtp server to listen from Ip2
4.1st virtual smtp sends unresolved addresses to 2nd virtual smtp
5.2nd virtual smtp sends unresolved addresses to external smtp
6. I create an event sink for 2nd virtual smtp to change the "fromto" and "replyto" fields
In this way:
If Outlook 2003 sends a message inside the domain, it is resolved by 1st virtual smtp.
If Outlook 2003 sends a message outside the domain, the message arrives to 1st virtual smtp using MAPI; then it is sent from 1st virtual smtp to 2nd virtual smtp using smtp language (not MAPI), so the event sink intercepts it and make all modifications; modifications are correctly executed because the message is in SMTP; finally the message is forwarded to the external SMTP server.
It works. Uff my boss now is calm.
