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.
