email-arch Section 2.2.2

  "The Relay performs MHS-level transfer-service routing and store-and-
   forward, by transmitting or retransmitting the message to its
   Recipients.  The Relay adds trace information [RFC2505] but does not
   modify the envelope information or the message content semantics.  It
   can modify message content representation, such as changing the form
   of transfer encoding from binary to text, but only as required to
   meet the capabilities of the next hop in the MHS."

RFC 5321 Section 2.3.10:

  "A "relay" SMTP
   system (usually referred to just as a "relay") receives mail from an
   SMTP client and transmits it, without modification to the message
   data other than adding trace information, to another SMTP server for
   further relaying or for delivery."

The draft says that a relay can modify message content representation 
whereas RFC 5321 says that a relay does not do any modification to 
the message data other than adding trace information.
