Yes -- a proxy can forward a SIP MESSAGE request to a mail server as easily as an INVITE request. Of course, the main server must be built to understand how to process the MESSAGE request and save it for the user. > Other question. In that messages, Is possible send Attached files? In theory, it should be no problem -- draft-ietf-simple-im-01, which defines the SIP MESSAGE request, says that the body of such a request can be any MIME type, which thus includes multipart/mixed, which is how attached files are usually sent. But that is likely to cause messages which are too large for SIP agents to handle. Better would be to have the body have type message/external-body, as discussed in section 5.2.3 of RFC 2046 and in RFC 2017.
