I sent email to a large private email list recently. I have gotten 20 “out of office” replies. This is dumb. The out of office robot ought not reply if the sender isn’t one of your correspondents for some reasonably definition of corresponent. How hard is that? For example if your have never sent X email and never replied to X’s email, and never even participated in an email thread with X, and X isn’t in my address book – what does this robot think it’s doing send X details of your personal life? There must be some really amusing stories of email robots revealing personal info.
