I even almost managed to find a copy of my old "mystery" mail (mystery because I've been unable to find in the archives, even though I know it has to be in there, as evidenced by the old print-out I have):

http://veps.hypertekst.net/misc/anon-remail/

Did find the thread, though:

http://cypherpunks.venona.com/date/1996/03/msg00168.html

Any chance I could get a copy of the full archive? (Email in profile in case you don't want to make the raw archives available over http).
