Here's a quote from RFC 974, "Mail Routing and the Domain System",
by Craig Partridge in 1986:

   Implementors should understand that the query and interpretation of
   the query is only performed for REMOTE.  It is not repeated for the
   MX RRs listed for REMOTE.  You cannot try to support more extravagant
   mail routing by building a chain of MXs.  (E.g. UNIX.BBN.COM is an MX
   for RELAY.CS.NET and RELAY.CS.NET is an MX for all the hosts in .IL,
   but this does not mean that UNIX.BBN.COM accepts any responsibility
   for mail for .IL).

"when in doubt, quote an rfc"
