A bit of hunting finally turned up mlist.com-priv: http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&group=mlist.com-priv but that's only a partial archive (not sure how far back it goes and I didn't see an easy way to jump to the first message). The thread http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&threadm=6n9a8n%24os5%40b5.eng.Internex.NET&rnum=2&prev=/groups%3Fq%3D%2522com-priv%2Barchive%2522%26hl%3Den%26lr%3D%26ie%3DUTF-8%26selm%3D6n9a8n%2524os5%2540b5.eng.Internex.NET%26rnum%3D2 or, if you prefer a concise URL: http://tinyurl.com/2xw3e has a pointer to http://www.mit.edu:8008/MENELAUS.MIT.EDU/com-priv/ which looks like a complete archive: http://www.mit.edu:8008/MENELAUS.MIT.EDU/com-priv/1 is dated 5 Oct 1990. The interface for the archive is not pretty.
