According to les@chinet.chi.il.us (Leslie Mikesell):

Of course, if a header field contains user@valid.domain.name, then any
mailer mangling that header field into valid.domain.name!user is being
Evil and Rude.

In any case, you're quite right; Smail 3's behavior in prepending its
host name is also Evil and Rude, and should be stopped forthwith.
Perhaps a public patch posting would be appropriate.
