You should be very careful, however, in mixing ! and @ style addresses.
There is no universally accepted standard (of which I am aware; I am
sure someone will flame me if I am wrong) regarding precedence.  The
only operator used with third-party mailing in @ addresses is "%".
Though many sites understand the above address and will process it as
Jean-Francois describes, other will (not necessarily incorrectly, since
there is no precedence rule) attempt to route the mail through attcan
to utzoo, expecting it to be sent to henry at uunet.uu.net.  If the site
on the rhs of the @ knows where the UUCP site is which you are tring to
reach (as in Jean-Francois's second example) you are probably safer
using %-style notation -- henry%ytzoo.UUCP at uunet.uu.net.
