E-mail predates UUCP. Tho, UUCP was the first time at which e-mail was broadly available outside of ARPAnet.No. When e-mail was introduced in the early days, it was based on UUCP.
Every incoming mail had an automatically generated return path (comparable to today's Received: header lines), but each single nodeAnd there's the rub. Anyone anywhere along the path could have forged everything previous to them. Not much different than the issues with SMTP. UUCP has _somewhat_ more node-to-node security than SMTP, but in the end it doesn't really mean much, because if you could get to the rmail executable, you could do just about anything - at least to the point of not being detectable by naive recipients.
had to authenticate against each next node in the path. But walking
back that recorded path, you had a full authentication path back to
the origin of the message (except for flaws of password authentication
and the weakness of the nodes themselfes).
