    Actually, on the topic of security and cryptography, I'd say the standards committees have failed the internet pretty badly. The apparent fixation with providing Verisign with revenue streams has gotten in the way of designing acceptable trust systems.

    The only result that the fixation with certificates and authorities has gotten us is a situation wherein everyone is becoming their own authority and nobody cares about certificate warnings anymore.

    If one wanted to repair the systematic damage by now, the best way would be to simply scrap the CA's out of browsers and anywhere else and just add a way to easily add specific CA's for each new domain/service provider one comes in contact with.

    Depending on the configuration of forwarding they will still have the original From: tho, so the way it usually works is like this:

    The mail will have the original From, and the rewritten headers indicating the mail came from the forwarding server. Upon googles SPF check, the SPF record will not contain the forwarding server as an appropriate or permitted sender for the From: field in question. The mail is rejected (or, rather, silently dropped).

    It's not a trivial problem to solve unless you have control over all the mailservers involved. You have to rewrite the From field so it no longer appears to originate from the original domain. It could rewrite with a valid name (something at the forwarding server), or by adding something to the domain name, creating a non-SPF protected From field, but however you do that you end up with a not-quite-accurate (or more accurate, depending on your view) From field. Which may cause problems in your client as you reply to the mail.

    If you have control of the destination mailserver, it's much easier: you could simply not check for valid SPF records for mails coming from the forwarding server.

Were, for example, the actions of SCO's leadership in the long and/or short term interests of the shareholders?

    Apart from the CEO selling the company real estate for $1 to his nephew, ie, outright fraud, it's quite hard to argue that company executive policy is not in the shareholders interest, no matter what it is. In the end, it comes down to opinions on how to profitably execute a business and maximize shareholder value.

    So saying 'it's the shareholders interests' is a meaningless cop-out. If shareholders don't agree with management on the way to maximizing profits they can vote to replace board and/or the executive or sell their stock. Arguing the CEO has to do what some specific shareholders want is, however, inane. The CEO can treat customers well, assist partners, pay high salaries and pretty much anything else that may or may not be in the immediate shareholder interest as long as he can make a reasonable case that long term shareholder value benefits and defend his actions to the board.

    Actually, it's government granted monopoly rights and marketing budgets that favour scale and mega-retailers. Channel control, payola and marketing costs get amortized over many more sales, making it very easy to crowd out most middle folks. Had it actually been a competetive field, people would have tended to buy the $1 Walmart print of the top ten songs, rather than the labels print, thus limiting the value of marketing by cutting the revenue possible to exact from the market.

    The internet and other technologies favour the smaller players as their costs are highly reduced, and as they are not as sensitive to marketing measures (never having a chance offline in that area anyway), they will do better than the midrange.

    Many small labels will die off; the only way they can avoid that fate is to rapidly adapt to the internet and cut their costs as much as possible (and sadly, there are many that arent even available in some online shops, leading me to really question their desire to survive at all).

So do you trust Microsoft? Your Firefox distributor? Do you trust the judgement of someone who considers Verisign trustworthy?
