RE: TECH OMISSION: Stronger checks against email forgery

["Jim Lyon" <jimlyon@xxxxxxxxxxxxxxxxxxxxxx>]

On Thursday, August 26, 2004 at 3:01 PM, Doug Otis argues: (via my
summary / paraphrase)

> That spammers will create messages that forge domains whose SenderId
records include "+all".
Yes, they will.  And those domains will get a (richly deserved) bad
reputation, and most people will refuse to accept mail from them.

> That other (unspecified) factors will cause many legitimate domains to
publish records with "+all".
I don't believe it.  I certainly haven't seen anyone on this list claim
that they intend to publish a "+all".

> That SenderID will cause the normal, person-to-person email message to
use something other than PRA == 2822 From == bounce address.
I don't believe this either.  Is there any support for this proposition?
If SenderID forces a change, then what will it change to?

> That all problems are solved if we merely implement
draft-otis-marid-mpr-00.
I (and many others on the group) disagree, for reasons stated many times
previously.
