Oops, this isn't true--as Arnt mentioned, RFC 5321 does require the presence of a from clause in the Received header field, although it says it SHOULD, not MUST, contain the name and IP address of host that was the previous hop.   This doesn't change anything, since there's explicit advice not to drop messages simply because they fail to meet this requirement.
