The "!" indicates a pathing; a source-route if you were, and "bang" seems
appropriate (bang off this, then that, then this, then you're there).

The "@" means what it says -- "AT".

BTW, mixing "@" and "!" in an email address is *extremely* likely to produce
other-than-intended results, especially these days.  Any site which is not
mapped with a real resolvable address (even UUCP connections) by this point
should be presumed to be unreachable or unreliably reachable.

A few years ago I ran one of the largest routing registries (built and
maintened automatically) in Chicagoland for "!" path email.  It was
completely retired a couple of years back as it had lost its usefulness.
