Anti-Spam Stuff

Checking up on the status of the (4) anti-spoofing measures that I know about. Here are links to my previous blog entries:

RMX Status - Aug 21 2003 - Research done in mid-August to determine where the status of the RMX proposal was. I also discovered (3) other proposals that I've added to the watch list.

Anti-domain spoofing - Aug 26 2003 - Links to the (4) proposals that I know about that attempt to tackle the "Is IP X allowed to send out e-mail for domain Y" problem.

All of these proposals need to answer (2) basic questions:

1) Does this domain have any sort of listing telling the world which IPs are allowed to send out e-mail for this domain?

2) Is a given IP on the allowed list?

Of course, the devil is in the implementation details. (Some proposals are more likely to break older versions of BIND then others for instance.)

Proposals:

RMX proposal - No news on Mike Rubel's page since June 2003. Not much on the official home page either. The last published draft is June 2003.

DMP - Last IETF draft published Aug 2003 and expires at the end of Sep 2003. However, version 5 of the document has not yet been posted and the author(s) does not have seem to have a central site to check for news.

DRIP - Last draft was published July 2003, expires Dec 2003. I don't see anywhere a central home page to check for news.

SMTP+SPF - Last update was mid-July 2003. I'm not sure if there is an IETF draft being floated or not.

Just a few links... (researching a topic again):

The Answer Gang 68 - Briefly explains whas reverse DNS is.

How Reverse DNS Works - or almost a reverse DNS FAQ.
