Re: [Asrg] A Technique for Universal Authentication

["Michael Kaplan" <michaelkaplanasrg at gmail.com>]

In your scenario a unique sub-address would be sent to myself and to John Levine, although it would also be quite acceptable to dispatch the same sub-address to each of us.

 

Anyone can use any sub-address.  You would receive John's email but as demonstrated in Figure 5 you would know that John replied to you using the sub-address that was originally sent to me.

 

John would only need to use a sub-address if his email received a poor rating from a Bayesian filter.

I sent a message to you and cc it to John Levine.

What value is put into the rfc2822.from field, the subaddress for mail
to you or the one for John Levine?

Further, if it is the subaddress tailored for you, then I cannot receive
a reply from John.
