Read the LMAP discussion document. It describes the real purpose of
LMAP: to stop non-consentual use of domain names in SMTP.
LMAP will have a similar window where it is useful by itself; once
LMAP starts to be widely adopted, spammers will start to adapt and
publish LMAP records, and we'll have to move on to reputation
services.
We already have reputation services: I know who "imc.org" is, and
I'm willing to accept mail from them. I don't know who
"get-port-now.com" is, and I'll probably delete all mail from them
unread.
The point is NOT to stop spam. The point is to separate accountable
parties from non-accountable parties. If all spammers sent mail from
long-lived and well-known domains, it would be MUCH easier to deal
with.
Still, there's a window when LMAP alone will be useful, and I think
that's what's driving a lot of the early adopters. By the time LMAP
becomes mainstream (and probably by the time this WG produces a spec)
that window will already be starting to close, with significant
numbers of spammers publishing LMAP records...
That will be WONDERFUL.
