"What is needed is "one-time addresses", or addresses that cease to exist after n messages arrive, where n is some low number suitable for you verification email to be mailed and maybe a couple more. Then it goes dark, and the mail server disavows any knowledge of you."

My SG account has eaten on the order of 10 thousand spams over its lifetime (a decade or so)

I personally find Spamgourmet to be more interesting...

You sign up (yeah, I know, you have to trust them) and give out email addresses like
madeupkeyword.X.yourusername@spamgourmet.org
where X is the number of messages (up to 20) that you want to allow for a particular word. Spamgourmet forwards X number of messages to your email, and then quietly destroys any further messages.

This is already done. It's called graylisting. Here's a website about it. Basically, you examine the unique combination of sender, recipient, and IP. The first time they connect, you return a "temporary failure" message. You continue doing this for a period of time (maybe about one hour), and then you accept the mail. The idea is that spammers, who use bulk-mailing programs, won't have the time or reason to resend a message, but that normal, well-behaved mail servers will. (This also means graylisting has to be employed on the mail server where the mail gets in. Once a "real" mail server receives the message, graylisting can't help.) I use Sneakemail, which is similar to Spamgourmet but a little more featureful, and it offers optional graylisting of addresses. I've used it on the (not spam armored) address posted on my website/blog, and it has filtered every piece of spam so far.

I'm running Gentoo Linux with a (unrelatedly) patched kernel. There are drivers for SpeedStep in the kernel; they're open-source.

If you go into Power Management options > CPU Frequency scaling, you will find lotsa options. You need at least one governor. I would compile all of them as modules. Then you pick "Intel Enhanced SpeedStep", and "Use ACPI tables..." beneath it. Then do "make" and "make modules_install", and try loading the new modules. You then need either cpufreqd or speedfreqd (or another similar utility) to monitor CPU usage and change speed. The kernel also has a module called "ondemand" that does what speedfreqd does (it is equivalent to the "dynamic" policy). I haven't tried it, but it's probably more responsive and efficient since it's in kernel-space.

If you have any more questions, email me at slashdot.thinkinginbinary@spamgourmet.org or IM me (AIM: thinkinginbinary/Jabber: name is thinkinginbinary, domain is jabber.org, with the usual character in between)

I used to use catch-all addresses, untill I found out about self-destructing addresses.

The idea is that you make up an address whenever you need one, and then the address is created the first time it is used, and destroyed after the specified limit is reached.

If you need to post your email address somewhere, but are worried about it being harvested, check our spamgourmet.org. You can create extra email addresses that are forwarded to your own, allowing you to tell where spam is coming from, and then tell it to delete any emails coming through that address.

Anyone who wants a Gmail invite, email me at gmail-invite-slashdot.20.thinkinginbinary@spamgour met.org.

You could also use SpamGourmet and give them dominos001.1.username@spamgourmet.org, dominos002, and so on...

Um, you haven't heard about spamgourmet yet, have you?

I've tried Spamgourmet. Excellent free service where you can do this:

1. Register a username like "foo".
2. Register at the MegaSpam forum.
3. Tell them your e-mail address is megaspam.2.foo@spamgourmet.com.
4. You will be forwarded the next 2 mails from the MegaSpam forum, probably containing password details as such things.
5. Spamgourmet will then eat all mails from the MegaSpam forum.

They also allow you to list trusted senders, which don't advance the message count for your temporary address, reply address masking, and password prefixes so others can't make up new addresses with your username.

Pretty nice, especially as it's free and no ads or other catches. They have around 14,000 accounts as of today and eats about 12,000 spams/day. :-)

And there's also despammed.org where any mails to that address will be filtered from spam before it's sent to your primary address or the web service. Everything on that site is free (and ad free) as well.
