In Sympa solution, archive are not passive HTML file as mhonarc output.
All pages are dynamically provided by a cgi. This allows a large choice
of control to archives such as :
-public but not for robot
-restricted to list subscriber
-restricted to list owner
-restricted local network
- ...
Any unauthenticated access or access without the cookie named
"not a robot" is redirected to a page for authentication or a
form to accept the cookie and access to requested page.
This way, what ever is the URL used to access some part of the archive,
access without the cookie is impossible.
Even if this mail is archived in a unprotected archives, the following
link will not be scanned by email sniffers:-) Try it !
