This, unfortunately, is true. I *have* to use a remailer to hide any
anon.penet.fi alias I have or the sender will see it and know I am
(for eg) anon1234@penet.

I balk at Yet-More-F******-Header-Lines (YMFHL) but a _possible_ patch
is to have a:

X-Show-My-Anon: yes|no       (in the header),

or:

::
X-Show-My-Anon: yes|no       (in the body)

addition so people who reply to a message from penet can feed their real email
address through the system rather than having it bounced to the recipient as
their anon id.  This would require either a smart mailer, checking exactly who
the orig letter was addressed to (your anon or your real address) and
inserting the line as appropriate. It *should* be automatic actually. All it
has to do is check a local list of your anon addressed and if someone has
mailed it then alter the above line as needed.

This raises question of the security of local lists of your anon addrs of
course.. but you get the idea..

Comments?

(BTW I saw someone's .sig where they *advertised* their anon id on USENET.
 Presumably this was because he thought thats what you had to do so others
 could email them anonomously... obviously he wont be a whistle blower :)
