@clacke Love this! UK academia were late with SMTP mail because we had our own "Coloured Book" protocols. Once it arrived the university I worked at used /bin/mail and MH with xmh on Ultrix, etc, then stuff like elm and pine. I was into exmh, a Tcl/Tk client on top of MH. It still exists and I use it manage mail on my local network. HTML mail was a horror once it arrived, primarily a repugnant Microsoft thing we felt. In no time our mail stores overflowed with unedited, top-posted messages!
