[dns-wg] DNS RMX records - e-mail sender authorization

[Hadmut Danisch <]

Hi,

I don't know whether this was discussed on this mailing list before.
I just subscribed and would like to hear your opinion about 

http://www.ietf.org/internet-drafts/draft-danisch-dns-rr-smtp-03.txt

which describes the RMX records, a method to store authorization 
records about who is authorized to send e-mails with sender addresses
of the zone. It is intended to protect against spam, worms, and such 
rubbish.
