Re: [Asrg] SMTP level unsubscribe

I'm worried that sharing the intersection of suggestions
with aspects of the system I've been working on is off
topic but here goes.

There is also the issue of which MTA would be responsible for 
doing this. For the simple situation where the recipient uses their
ISP's POP/IMAP servers to receive their mail, it might be relatively
easy to send consent details to that ISP's server MTA. To try and
communicate such data into other MTAs closer to the network core
would be much more difficult due to the sheer volume of data.


I see no advantage in adding a command from a different layer to
SMTP.  Variable envelope return paths work perfectly well for the
purpose Scott Nelson suggested.  Andrew Akehurst suggests that
a receiving MTA could be hacked to refuse selected messages.  This
is similar to a suggestion made on a talk-radio show last week,
the show was on spam, Missouri might be rolling out a law against
return address forging.  A caller suggested adding a "bounce" button
to their MUA in addition to the "delete" button.

The pay2send MTA, which I am and havebeen working on, will use rules
to allow wanted messages in, and block all else.

You can set something up with sendmail milter, too , I think.
