Have I understood correctly? Would address filtering give you what you
expect to get from such a cookie?
You understood perfectly what I want to do. :-)
Cool.
But address filtering would not do the same for some reasons:
- The mail address is not secret. As long as we don't have a
spoofing protection, anyone can fake it. E.g. if this is used
to give you posting access to a mailing list, anyone would
know your e-mail address, but you would know the cookie only.
I think this need would be met by the existing "no spoofing" goal. (I also
note that a cookie would be a fairly open secret and also open to
spoofing).
- At least the german privacy laws do not allow to have databases
of individual data - such as e-mail addresses - under all
circumstances.
I don't know about this. My (worthless) opinion is that a list of email
addresses used for filtering should be equivalent to a list of email
addresses as an address book, which should be permitted.
So, I can't think of a way to phrase the "cookie idea" as a mail-ng goal
and actually think your goals could probably be met without it.
Interesting thought experiment though.
