Yes, exactly. :-)
I can see some potential use in this, but wouldn't it be better to have a
method to instruct your local mail system to perform the same filing
actions on all email from that particular address? Particularly since the
recipient may change MUA?
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. :-)
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.
- At least the german privacy laws do not allow to have databases
of individual data - such as e-mail addresses - under all
circumstances.
