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. -- Chip Salzenberg at Teltronics/TCT , "What's that thing, when people die, they take apart the body to see why?" -- St. Theresa of the Net
