I believe it varies from state to state, but this is indeed the norm.

Why stop at authenticating signed messages?  I'd like to see some mailing
list software that would send mail out to you encrypted if you want (sure,
the list is probably public, but you might not want people knowing you
subscribe. If list traffic was encrypted, and you routed it through Ghio's
remailer-alias doohickey, the fact that you subscribe could be kept
completely hidden), and would require authentication on a message to change
your address, or to change your public key (which would also be possible).
And would have config parameters such that the list operator could make it
only accept signed submissions, or even only accept submissions encrypted
to the list.  [not that I'm advocating this on the cypherpunks list, but it
might be good on other lists, especially private ones].  And Ideally, I'd
even like the list to be able to mail to you through the remailer-net, by
prepending your encrypted address block, and sending to a remailer.
Although the existence of Ghio's forementioned doohickey (what is that
service being called?) makes that somewhat superflous.

I was planning on writing such a beast myself, and might still get around
to it eventually. The problem is that I'm unlikely to write something from
scratch as robust as the current list server software (I'm not interested
in writing good list software, just in implementing the crypto), and I'm
not really skilled enough to understand the majordomo code enough to modify
it.  But I might try, one of these days.
