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.

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.
