According to the bad144(8) man page: 

it got added in 4.1BSD. According to CVSWeb, it got yanked from 4.0; it  
was still present in all 3.x and 2.x releases:

Important. Antidisclaimer. This e-mail is not and cannot, by its
nature, be confidential. En route from me to you, it will pass
across the public Internet, easily readable by any number of system
administrators along the way. If you have received this message by
mistake, it would be ridiculous for me to tell you not to read it or
copy to anyone else, because, let's face it, if it's a message
revealing confidential information or that could embarrass me
intensely, that's precisely what you'll do. Who wouldn't?

Likewise, it is superfluous for me to claim copyright in the
contents, because I own that anyway, even if you print out a hard
copy or disseminate this message all over the known Universe. I
don't know why so many corporate mail servers feel impelled to
attach a disclaimer to the bottom of every e-mail message saying
otherwise. If you don't know either, why not e-mail your corporate
lawyers and system administrators and ask them why they insist on
contributing so much to the waste of bandwidth.
