The majority of all spam comes from home computers infected with a worm that makes it part of a botnet. The fact that some mail servers can slow down the sending of mail is not the solution. If ISPs were to block all SMTP connections from their DSL/cable customers, that would put a huge dent in the amount of spam. Most people get their email through some sort of webmail based system so there is really no need for people to be sending legitimate emails via SMTP. And for the ones that like to have their Thunderbird or Outlook express send their email, there is probably a way that you can make the client get the email through the web system the same as the way Outlook can be retrieved over SSL. Block users from sending SMTP and you block most of the spam on the Internet.

If you read Bill Gates' original prediction, he said that spam would be killed through the electronic equivalent of a stamp, also known as "payment at risk". This means that if an email gets marked as spam, then the sender will be billed for a cost whenever they send a spam email. He didn't say that users would not have to deal with spam, he said that spam would simply not exist altogether. This most certainly did not happen, so he was completely wrong in his prediction.

As he said, once they thaw you put them back outside to freeze again. But even if you didn't, it would actually still be ok to leave them in since a refrigerator is more efficient with more things inside than with less. This is because there is less air that needs to be cooled when the door is opened and all the cold air escapes.

What they know about you is only what you tell them.
