8/16    Why does my Y! mail account always full of unfiltered spam
        mails (and they're obviously spams)? Why can't they do
        a better job like Google mail? Why does Y! mail charge
        for exporting email? Google mail doesn't do that.

        Spam King kills himself and his family after escaping prison

        Hopefully more spammers will take the hint.
        \_ I wish the same fate can go to all marketing and
           advertising folks, selling people things they don't

7/17    Thanks to steven, et al. for restoring Soda. In lieu of www.csua providing
        status, could there be a text file with current status and future plans.
        I'm wondering if SpamAssassin is obsolete (and my procmailrc and scripts)
        and won't be restored, and what's filtering spam now.  thanks!
        \_ How do I buy steven a beer or donate gobs of money?
           \_ I got him a Hacker-Pschorr, he seems to like ales.  Prob IPAs

5/4     Is mail still down? I don't seem to be getting any and vermouth
        is unavailable. I saw a note saying it was down Sunday, but it's
        almost Tuesday now.
        \_ exim4 decided it wanted to just die. With the same config file and
        everything. Steven spent all weekend and a lot of yesterday migrating
        to a VM. A side effect is that NFS is now no longer on Keg, so crashy

Spam is back, and worse than ever Posted: Friday, January 19 at 05:00 am CT by Bob Sullivan If you feel like your inbox is suddenly overrun with spam again, you are right. Not long ago, there seemed hope that spam had passed its prime. Just last December, the Federal Trade Commission published an optimistic state-of-spam report, citing research indicating spam had leveled off or even dropped during the previous year. Instead, it now appears spammers had simply gone back to the drawing board. In fact, there's twice as much spam now as opposed to this time last year. About half of all spam sent now is "image spam," containing server-clogging pictures that are up to 10 times the size of traditional text spam. And most image spam is stock-related, pump-and-dump scams which can harm investors who don't even use e-mail. "Traditional methods have failed spammers, so they are resorting to more and more sophisticated tactics," said Dave Mayer, a product manager at IronPort, which makes anti-spam products. There are 62 billion spam messages sent every day, IronPort says, up from 31 billion last year. Now, spam accounts for three of every four e-mails sent, according to another anti-spam firm, MessageLabs. Image spam is a big part of the resurgence of unwanted e-mail. By using pictures instead of words in their messages, spammers are able to evade filters designed to detect traditional text-based ads. New computer viruses have contributed to the uptick, also, particularly a surprisingly prolific Trojan horse program called "SpamThru" that turns home computers into spam-churning "bots." Some small organizations are having real trouble with the spam surge, IronPort officials say. One county government office called the firm after its mail server shut down. "(It) could not even slowly process mail," said IronPort spokeswoman Suzanne Matick. "They ended up with no mail going to their 7,500 users for seven days." She declined to identify the agency, citing confidentiality agreements. Of course, there wouldn't be this much spam if it didn't work. Concentrated stock spamming has the ability to send share prices of penny stocks soaring, said Graham Cluley, a consultant for computer security firm Sophos. Last summer, California-based Southern Cosmetics was forced to issue warnings to investors after spam campaigns touting shares of the company. During one such campaign, the firm's stock value rose from below 1 cent per share to a high of 66 cents. The Securities and Exchange Commission has prosecuted some spam pump-and-dumpers, and on other occasions, has suspended trading in firms after it spotted a spam campaign. But the agency can hardly keep up with millions of stock spams each day. Attempts to manipulate stock prices through e-mail are nothing new, said John Reed Stark, chief of the Securities and Exchange Commission's Office of Internet Enforcement. But despite the agency's "hefty track record of bringing cases" against spammers, the technique persists. No clicks required Stock spam is effective because no Web link is required, Cluley said. In old-fashioned spam, criminals generally try to trick recipients into clicking on a link and buying something. Many e-mail programs now block direct Web links from e-mails, rendering click-dependent spam much less effective. But stock messages merely have to make the recipient curious enough about a company to motivate him or her to buy a few shares through a broker. There is another element that helps perpetuate stock spam, Stark said - he believes speculators unrelated to the original spam sometimes try to "play the momentum" surrounding a spam campaign - either getting in early on a pump-and-dump campaign to profit as shares rise, or by "shorting" stocks, betting that they will fall after the spam campaign flames out. "There are all these people pushing the envelope in sometimes desperate ways to try to make money," Stark said. Image spam, which seems not inseparable from stock spam, can arrive entirely devoid of text, but that's not common. Most messages have what appears to be nonsense text pasted above and below the image. Experts call this "word salad," or "good word poisoning." Below this story, we've pasted some examples of what we call "spam haiku." Here's one: "I thought I was Train cars derail, catch fire in KentuckyMassive fireIdol begins this week!" The seemingly random text actually serves and important purpose -- to foil or confuse word-based spam filtering. Many spam filters determine the likelihood that a message is spam based on the individual words in the body of the e-mail. The presence of obviously spamish words like "Viagra" or "sexy" tilts filters to categorize a mail as spam and block it or route it to a junk mail folder. But because normal conversational words tend to persuade filters that a message is legitimate, spammers paste in bits and pieces of text to fool the filters. There's debate about how well that trick works, but there's no debate about how much word salad there is - it's everywhere. Spammers continually refine and combine their techniques, said Doug Bowers, senior director of anti-abuse engineering at Symantec. The firm recently found spam attached to legitimate newsletters that appear to be from big companies, including a Viagra ad atop a 1-800-Flowers e-mail newsletter and another on an NFL fantasy league letter. Such e-mails are simply spam masquerading as authentic, with real content borrowed from legitimate companies. They are similar to phishing e-mails, and so are much more likely to be opened by recipients than traditional spam, Bower said. "They craft an e-mail that looks like a newsletter, but change as little as a single line and insert an image," Bower said. "As in phishing, they are copying the look and feel of the legitimate e-mail." One way companies are combating image spam is to turn off all images arriving in inboxes. But that can be a draconian measure, as it will cut off pictures of grandchildren, too. Spotting spam before you open it is a plus -- sometimes spam messages contain small images that report back to the sender as soon as a message is opened, teaching the spammer that your e-mail address is valid. But in some cases there is no way to tell if a message is spam without opening it. So for now, the best defense consumers have is their delete key -- and a heavy helping of skepticism when investing based on anonymous tips. The SEC's Stark puts it bluntly: "Never invest based on spam."

EMAIL THIS 119 COMMENTS Most of this spam is coming from PCs that have been hijacked and which pump out thousands of emails a day. I fail to understand why ISP's can't detect when a customer's computer is pumping out spam, suspend its service, and alert the customer that they have an infected computer. If ISPs are reluctant to take this step for fear of alienating customer...
