A long time ago I subscribed to the security announcement list, and I’m receiving announcements since then. However my E-Mail address had changed, and the messages are forwarded from the old address to the new one.
As it seems the current list server does not support a change of email address, and I cannot remember any authentication data for the list server (in case there would be a web interface to change the address).
The list server responded to “help”:
confirm - Confirm a subscription or held message request.
echo - Echo back your arguments.
end - Stop processing commands.
help - Get help about available email commands.
join - Join this mailing list.
leave - Leave this mailing list.
stop - An alias for 'end'.
subscribe - An alias for 'join'.
unsubscribe - An alias for 'leave'.
who - Get a list of the list members.
