Summary: user@foo.COM == foo.com!user

You should be able to specify a route like

	site1!site2!host.domain!user

as an alternate to

	site1!site2!user@host.domain

Sites that gateway between @ and ! networks should be able to
grok host.domain!user for this very reason (according to the
RFC you love to hate :-) If you look at the paths generated
by smail, they will use the host.domain!next_part convention in
preference to user@... to enable these type of addresses to
be routed through hosts that understand @ as well as ! without
any confusion arising.
