I don't think there is an RFC specifying that a server must accept 
whatever crap. http://tools.ietf.org/html/rfc2821#section-3.3 just 
says that << If the [return-path] mailbox specification is not 
acceptable for some reason, the server MUST return a reply indicating 
whether the failure is permanent [...] or temporary. >>
