Once more with feeling.
We've made our interest in Sender ID for E-Mail no secret, from pointing out its potential value to upbraiding Microsoft for playing patent games with it. Elsewhere, we've addressed why the standard needs to be as unencumbered as possible.
The Apache Software Foundation, best know for its Apache Web server (define) but also the host to a variety of software projects, weighed in this week on the matter of Sender ID for E-Mail, and why no Apache Foundation project will utilize the technology:
"We believe the current license is generally incompatible with open source, contrary to the practice of open Internet standards, and specifically incompatible with the Apache License 2.0. Therefore, we will not implement or deploy Sender ID under the current license terms."
Microsoft's rebuttal? "... our intentions are 100 percent pure."
Unfortunately, that won't cut a lot of mustard with developers working under the ASF's umbrella, including the developers with the SpamAssassin project, which is currently featured in our series on building a Linux-based anti-spam/anti-virus gateway (see parts one and two).
The good news is that the non-Microsoft part of the specification features no patent encumbrances, and it's still fairly useful on its own. Microsoft's contribution isn't mandatory.
We have one other comment on the SPF matter before leaving it to our upcoming series on deploying and using it under Windows and Linux:
Recent reports have noted that spammers are eagerly setting up SPF records for their domains at a rate exceeding that of even legitimate domains. This is occasionally taken as some sign that Sender ID/SPF are somehow dead out of the gate.
It's important to remember, as with any technology, that no one in their right mind would claim Sender ID will "solve" the spam problem. What it does do is create a layer through which all mail must pass. If a known spammer is making a pest of himself, then proof that he's sending from a given domain makes filtering that domain a beneficial and useful step in screening him. If he moves to an unregistered domain, tools like SpamAssassin and others can be taught to weight the "credibility" of such a domain when assessing whether a given message is spam or not. When you're building the better mousetrap, you need more than just the piece of wood, the cheese, or the big spring: You need all the pieces working together.
SenderID is one of those pieces.
Now if only we could work out the whole patent problem.
