Jon Postel participated in many online forums such as the tcp-ip mailing list.  To access them, I’ve been using the archives at ban.ai, but I can’t access them currently.  They’re also available via Google Groups, but unfortunately there’s a lot of spam there.  You could also visit the IETF mailing list archives that go back to 1992.

One of the best things about this list is first hand accounts of our
internet lore

Does anyone have any stories about working with or near John they would
like to share with the list? It would definitely make my day to hear more
about the early internet

Thanks,
