Re: Internet mail in the 80's

Hi Bob:

UUCP gateway and internet email gateway became effectively the same thing
c. 1987.  That was quite a change.  It used to be that you'd have to route
to an UUCP host that was connected to ARPANET, so some set of bang paths
to, say, seismo, which would then interpret the remaining address as an
Internet address.  Email gateways spent a lot of time crafting return
paths, so someone could reply to a message that originated on a different
network.

But the combination of domains names, and pathalias (I think that's the
name - in any case, work by Honeyman and Bellovin to automatically route
within the UUCP network), and MX RRs in the Internet world (which allowed
us to email to domains that weren't on the Internet [yet]) meant you could
email to someone at 3com.com from UUCP, Internet, or CSNET (and later
BITNET) and it just worked!

This was intentional and reflected considerable work by folks to make all
the parts integrate well during 1986 and 1987.
