Seems to me the really important issue here is to make it clear that once the mail is sent, it's gone, it's just mail, and listserv has nothing to do with it. So, can you _ever_ be sure your email's been opened? I don't think so. Not if it's coming to me, because I invariably disable the function that would acknowledge receipt or opening. I do it in part because I don't think it's anybody's business whether I received or opened their mail till I _tell_ them it is, and in part because I don't want to automagically tell some spammer that this is a live address. > Though Eudora has the option, the Eudora recipient can negate it. I'm appalled that any mailer wouldn't come with it turned off by default (but not actually surprised). -- Russ Russell Hunt Department of English St. Thomas University http://www.stu.ca/~hunt/
