I disagree, it's easy to bounce mail through ANY Internet-connected
host running sendmail and thence to a remailer.

In fact this mail was sent that way, I bounced it through sun.com
before hitting a remailer.

Only if the Backbone Cabal (there is no Cabal) is re-formed
(and given special SuperPowers!) with the sole purpose of
blocking Dimitri from posting to cypherpunks.

The address you mailed to is no longer valid.
This is probably because the user in question was an
old Open Net subscriber. Open Net is NO LONGER an ISP,
and has not been since May 1996.

We have no redirection address for that user. Please
remove them from any mailing lists you might have.
