Note that the RFC only deals with the SMTP transport activity, not
local delivery.  The local part of the address is handled locally,
so while the transport can't make assumptions, the local system
can do whatever it wants.  So, we have a system where User at remote.site
may or may not be the same as user at remote.site but odds are
pretty good that he is.  But, User at local.site is going to be the
same as user at local.site on any unix-like box unless you have done
something bizarre (which is allowed...)  Aren't standards wonderful?
