The point of ADV is it would let me block all commercial mail from
entities not in my whitelist.
Which would be just fine by me.
This assumes that there is a reasonable whitelist system out there
that doesn't block mail from N-different addresses at your favorite
vendor, but does block mail from forged addresses (say
support(_at_)microsoft(_dot_)com?) at the same vendor. And it needs an easy
protocol for clicking on a link on a web site and whitelisting that
site. And it needs to be understandable and usable by the general
public. (And even then it doesn't do much good for those of us who
regularly get mail from people we don't know.)
I've said before. If everyone is going to be depending on
whitelists--someone should start figuring out how a mailing list
and/or web site communicate with the whitelist software on your
machine. (E.g.
whitelist:domain=amazon.com,localpart=bounce-[username]-[domainname]...
or whatever).
..
I'm not a fan of ADV tags particularly on "commercial mail" (if I send a
purely ASCII message to somewhere.com offering to buy or sell something,
must I tag it with "ADV" and include an opt-out URL?), but your criticisms
are based on notions that don't make sense to me:
- that mail from people you don't know and that you want would be
marked with "ADV". Would you really want unexpected and so
unsolicited advertising?
- that mail senders need to communicate with your whitelist software.
Why? If envelope and headers are not forged, then when you decided
you want blue pills that grow loans from deals4u2buy.org you can
whitelist mail from deals4u2buy.org by pointing and clicking purely
on your own system. At worst you can start watching your logs of
rejected mail and click on a caught sample to whitelist it.
- that Deals4u2buy.org will use N-different addresses. On the
contrary, they'll good reasons to tell you their sender domain name
and to keep it constant.
- on the other hand, if the envelope or headers are forged, then
the "ADV" tag will also be missing, because a large minority and
probably a substantial majority of all users will decide (or have
already decided) they want nothing tagged with "ADV" except perhaps
a few white-listed exceptions.
- Why can't people understand ADV tags and whitelisting? I don't recall
encountering anyone who couldn't but who could handle email. Proof
that people can understand this stuff is in the fact that so many
of less sharp among us who have been elected to legislatures are
so enthused about their laws requiring ADV tags.
- we already have standardized mechanisms for identifying mailing lists.
RFC 2919 is on the standards track.
