This seems unnecsary to me, since RFC822 compliant address can still
specify routing.  The syntax for this is @host1:@host2:user@host3.
I've been told that the ":"'s should be ","'s except for the
right-most one (as the Berkeley sendmail configuration does), but I've
been unable to find this stated in RFC822 (could someone send me a
reference, if the ","'s are actually correct).
