Re: Email peering

Similar concept, same scaling problems; it just hides the explicitroutingfrom the user (as would any modern "peering" system, presumably).
One way that it COULD be implemented is for people acceptingDNSWL -- this is already being done. It is not widely viewed as being in any way similar to a peering concept. What would be more similar would be a consortium of large providers providing such a whitelist. That would be something I would welcome.
I would settle for having aol,msn,yahoo,earthlink,cablevision or any half dozen providers making public THEIR whitelists.
The problem is that there does not appear to be any incentive for them to do so -- fee or no fee.
In fact, I would encourage anyone planning on ragging on DNSBL's to put up AND shut up, namely operate a DNSWL.
Existing public whitelists include:
To use it with sendmail:
To use it with spamassassin:
header XXX_DNSWL eval:check_rbl('xxx-firsttrusted', 'xxx.ttec.net')
score XXX_DNSWL -5
Anyone else with a public DNS whitelist?
