	Domain Yahoo
		The domain owner, or an agent or service provider acting on their behalf, should generate the key pairs that are used for their.
		Keys: Set up: The domain owner typically the team running the email systems within a company or service provider generates a public/private key pair to use for signing all outgoing messages multiple key pairs are allowed The key length is decided by the domain owner.
		Keys and then tell the world this policy so that email service providers can watch and drop any messages that claim to come from their domain that are unsigned.

	DomainKeys - Wikipedia, the free encyclopedia
		The default parameters for the authentication mechanism are to use SHA-1 as the cryptographic hash and RSA as the public key encryption scheme, and encode the encrypted hash using Base64.
		The receiving SMTP server then uses the name of the domain from which the mail originated, the string _domainkey, and a selector from the header to perform a DNS lookup.
		The domain owner can then focus their abuse team energies on their own users who actually are abusing their use of that domain.

	Computer security system - Patent 4584639
		The keys node 13 is used to hold keys 16 to be invoked by the domain 11 or passed as key parameters.
		Since the domain keeper has a domain key to the trapped domain and the author of the domain keeper is free to use all of the domain's capabilities, the author of the domain keeper's process is free to design any response to any type of fault that is within the capabilities of the domain.
		Segment keepers receive, as key parameters 2 and 3, a node key to the red segment node in whose segment the memory fault occurred and a fault exit key to the domain that caused the fault.

	Domain Keys
		The domain key grants its holder the ability to extract and insert all of the data and keys that would be available to a process running in the domain.
		When a domain is created an extra node N is created and the only domain key is kept in N. N is formatted as a red segment node with the domain key in the position of the segment keeper.
		If the invoked domain and the returnee share nodes but are not the same domain, then {1} the situations of (p1,worsejump), SC = 48 and 49 are possible, and {2} if the order code is 70 {read registers} the return may not occur.

	broadband » News » Domain Keys Trial - Yahoo launches Earthlink trials
		Yahoo has announced the company has started testing their Domain Keys e-mail authentication technology (see previous report here) in conjunction with Earthlink, which they hope could become the industry standard.
		Your Thawte key covers only the content, and is in fact a stronger indicator of authorship than the Domain Keys signature.
		Domain Keys on the other hand is an attempt at automating digital signatures.

	Sender ID Declines, Domain Keys Shines
		In the Domain Keys scheme, both the IP address of the sender and the digital signature of the sender's message must match.
		Domain Keys doesn't require the encryption of an entire message, but it does require the signing of a snapshot or "hash" of the message.
		Domain Keys "will prove to be far more efficient than current methods of filtering and evaluating all messages," Sendmail said in its findings.

	Weblog for Costin Manolache: Yahoo Domain Keys
		Unfortunately, just like SPF the yahoo domain key solution is based on DNS and would lock out small sites using their own SMTP servers without a DNS entry.
		Domain keys would either force everyone to get a DNS domain and DNS server supporting that entry, or will force people to use "big operator" servers.
		IMO the only way a key solution could work is to make it flexible enough - the information that Yahoo or some other domain was indeed the originating server for the mail is very valuable as it locks out a lot of fake mail.

	Yahoo Proposes Anti-Spam Standard For Internet
		For e-mail the sender might sign each message with his or her private key, and after looking up the sender's public key in some publicly-available system, usually a certificate authority, the recipient could confirm that the message was in fact signed by the person claiming to be the sender.
		Yahoo's Domain Keys proposal has two interesting innovations that make it different and intriguing: First, authentication is only performed on a domain level, not the user level.
		Domain Keys would also present a problem to users (like me) who use a From: address with a domain different that the one for the SMTP server sending the message.

	DomainKeys Distribution Options
		The most general key distribution mechanism is for the email administrator to generate the _domainkey records to give to the DNS administrator.
		Administrators may feel that the risk of a key being broken is too great or has decided to make a change in their outsourcing.
		Before removing a key from DNS, a new key should be put into the DNS records and the outbound MTA should begin using it.

	Auto Keys Versus Domain Keys
		Identify and enforce all the domain keys, that is all the valid business rules that dictate that a combination of attributes (columns) should be unique (or identifying) over an entity (table).
		Some people believe that record or object keys should be system-generated (auto) integers, while others believe that there are natural "domain keys" such as social security numbers, person names, or a combinations that should be used.
		Using surrogate keys as a mean of implementing foreign keys, is not always the best option, but it has to be taken on a case by case basis.

	[Spambayes] RE: Yahoo's "domain keys" and spam (Site not responding. Last check: 2007-11-02)
		But there must be some method of establishing a "trust level" for authenticated sending domains, otherwise all the spam-houses will simply put public keys in their DNS, install the signing feature on their MTA's, use "real" domains in their messages and continue as before.
		In the Yahoo case, this would be verification of the signatures) The Yahoo verification would also require the calculation of a hash of several strings from the message header (sending domain, timestamp, etc.), but this is computationally trivial once the mail message is in memory.
		I would guess that performance of message verification using Yahoo domain keys would be of similar.

	Proposals Offer Small Steps to Stop Spam
		This domain would be queried to see if it held an "E-Mail Policy Document." This document, a file up to 2048 bytes in length, would be written in XML format and would, like SPF, specify a list of legitimate IP addresses for outgoing mail.
		The owner of a domain name would post a "public key," which would be checked by any mail server that received a message purporting to be from that domain.
		If the key lined up with the signature of the message, the receiver would be assured that the mail, in fact, did originate from a sender at that entity.

	LWN: Domain Keys for email sender authentication
		The domain in the "From:" (or, in some cases, "Sender:") header must always match the domain in the DK header and that provides the linkage that verifies the sender.
		Your message is right on--if Domain Keys were simply a key management mechanism and not a new message format, we'd be a lot closer to practical email authentication.
		Domain keys certify that the message was sent from a certain domain.

		Domain Keys, on the other hand, looks a lot more promising.
		Domain Keys essentially provide the same sort of 'anti-forgery' system as SPF, but in a different way.
		This essentially means that, for now, the Domain Keys proposed standard is considered broken by many email experts, and will need to be changed before it'll be workable.

	It is time for mail administrators to learn about DomainKeys, a new (for now useless) standard aimed to separate spam ...
		The sender side makes a key pair with a public and private key what will be used for signing.
		The private key is added to the MTA program and the public key is published in DNS (Domain Name System) records.
		As domain names are cheap at only $10, it's a small issue to register a new domain, add the right records and keys, send spam until it is fllisted and then just move along to the next random domain name.

	Yahoo, Sendmail to test antispam system \| CNET News.com
		Key to thwarting spammers is developing methods to verify that people are who they say they are.
		DomainKeys is a proposed system that attaches encrypted "keys" or tags to every e-mail sent--with one key held in a public database and another key, which is private, linked to the message.
		Once the message is delivered, the receiver could match up the private key to the public key held in the open database to verify the sender's identity.

		Yahoo said its "Domain Keys" software, which it hopes to launch in 2004, will be made available freely to the developers of the Web's major open-source e-mail software and systems.
		Governments around the world are working on legislation to reduce spam, but in the interim a number of companies have stepped in with technology proposals designed to filter and block the electronic detritus.
		If the public key is able to decrypt the private key embedded in the message, then the e-mail is considered authentic and can be delivered.

	Simon Willison: Domain Keys Explained (Site not responding. Last check: 2007-11-02)
		Essentially, mail servers generate a public/private key pair and sign outgoing messages with the private key, while publishing the public key as part of their DNS record.
		Because only they can publish to their public key in this way the signature can be used to confirm that the sender of the email has not been spoofed.
		They were all hosted at Interland at the time, but after all the gripes I ended up walking from Interland and going with a different host and then outsourcing the mail to an email security/spam filtering company, I ended up choosing Sentinare for their spam filtering.

	broadband » News » Yahoo 'Domain Keys' - E-mail authentication without a King Maker?
		This certainly sets up a couple groups to make a bucket-load of new money: the third-party trusted signers (e.g., Verisign) and companies that would provide such trusted DNS zones (because a significant number of current DNS zone owners are not going to be able to afford to run their own after implementation of this).
		If the mail comes from a domain that has been cryptographically determined to be correct, the spam score will decrement by some amount.
		In this case, one is going to have a little bit more challenging time figuring out which key signatures one will trust because there are a lot more of them than just the VeriSigns, GeoTrusts, and Equifaxes (etc.) of the world.

		Yahoo this week announced they're working on an open-source software that uses public key cryptography to digitally sign e-mail and verify its origins.
		E-mail passing through blessed servers will be tagged with a cryptographic signature as it passes through the mail server.
		Email clients or en-route mail servers can then check the e-mail's header, and compare it to a public key shared via DNS zonefiles to confirm authenticity, presumably dropping the message if something is wrong.

		It looks like that will be the case.
		It won't stop spam alone since spammers running their own servers could easily setup key pairs, although it would be easier to trace and then fllist these servers.
		Also, if a mail server is an open relay, then won't it just accept and sign any incoming mail then pass it on?
