I didn't understand exactly what you were doing before.  The
install{world,kernel} must be executed on the same architecture (and
similar FreeBSD version) as the build{world,kernel} because the
install{world,kernel} executes code that was built as part of the
buildworld.

Rather than NFS mounting the buildhost onto the target and running
install{world,kernel} on the target, you need to NFS mount the target
/ and /usr onto the buildhost and use DESTDIR to point the install at
the correct location.  This will work, modulo some chflags issues
(chflags isn't supported over NFS - I don't recall offhand where this
is discussed but google should be able to help).

an MTA that is either RFC2821-compliant or matches their claimed behaviour.
