There where in the wild implementations x.400 and x.500 I worked on them.
And x.400 had stuf that internet mail took a decade to catch up to and some cases does not have non repudiation for example.
- ChrisMarshallNY 6y agoThis is true. I worked for a company that ran X.400 commercially, before the Internet really got going. It did, indeed, have many things that we wish email had, these days, like true read receipt and routing management. But it was a complex beast, and that is why it lost out to simple SMTP and POP.
- Mauricebranagh 6y agoOh cool which one
- ChrisMarshallNY 6y agoI normally don't mention the names of companies with which I worked in social media posts, but Dialcom has been dead a long time. I don't think it matters. They also used PRIMOS. I worked in FORTRAN (4), PL/1, and C.
- Mauricebranagh 6y agoOh small world me to I worked for Telecom Gold who ran the UK service (in the many varied corporate structures). What would be really strange if you worked on GLE a PL1/G program the US side made for our Billing system.
- ChrisMarshallNY 6y agoNah. My PL/1 stuff was all original. The legacy stuff was FORTRAN. Did I say 4? My mistake. '77. A hundred KLoC of spaghetti, just like Mama Mia used to make. The X.400 stuff was in C, but I'm not sure that the stuff I worked on made it to the customer. We wrote a mover application.
