Here’s a gem from today’s postmaster mail:

Mailer-daemon, You’ve received a postcard!

You have just received a virtual postcard from Aunt Edna!

Uh huh. I know some software projects have enough history to have family trees, but this seems just a bit too unlikely!

Various outlets have reported on the recent appearance of evangelical spam—unsolicited bulk email which promotes religious messages instead of advertising products. It’s been pointed out that since CAN-SPAM refers to commercial mail it can’t be used to stop people who bombard you with other types of messages.

I’ve seen 419 scams with religious trappings for months. These are the usual “Help me smuggle $20 million out of my country” ploys with the added twist of “Oh, I’m a missionary” or “I’ll donate it to an orphanage” or “You can trust me, I’m a Christian,” usually tied to a middle-eastern nation where Christians are in the minority (because Nigeria is so passé). Of course the only thing the scammers really worship is the almighty X-MILLION US DOLLARS. It’s a cheap sympathy ploy, nothing more, made obvious by the fact that, well, it’s a scam!

Today I saw a new variation on that tactic: instead of appealing to Christians, this one was appealing to Muslims. It was all about some Muslim convert in Cuba who had been abandoned by his Catholic family and just needed to transfer $12 million out of the country… all sent from a UK-based email account.

On a side note, I’ve found myself wondering lately why so many of these seem to come from European ISP Tiscali, particularly Tiscali UK. (One came through yesterday with 119 copies of the standard footer!) I assume they must provide easy-to-get email accounts, or perhaps connectivity for a lot of Internet cafés. It also suggests that quite a few of these scammers aren’t anywhere near the (mostly) third-world nations where they claim to live.

CAN-SPAM one year later: more spam than ever. Spam has more than doubled from 15 billion messages in 2003 to an estimated 35 billion in 2004. Is anyone really surprised? From the article: “The FTC says the goal of the act was never to cut down on spam but to give recipients control via the opt-out component.” Hmm, that might be part of why groups like Spamhaus were calling it the “You Can Spam” act. (via The War on Spam)

Webroot identifies the Top 10 “Most Unwanted” Spyware programs, using the “P-I Index…. P is for prevalence, I is for insidiousness.” The “winners” include pop-up generators, keystroke loggers, autodialers and the like. (via Aunty Spam’s Net Patrol)

Finally, there are several fixes and work-arounds for the pop-up window spoofing vulnerability I wrote about last week. There’s the all-inclusive method: close all other browser windows. Netcraft reports that Opera has issued a fix (7.54u1) and Safari is safe if pop-up blocking is enabled. I just got an email indicating that KDE has released a fix for Konqueror (expect that to start hitting distributions this week). No word yet on Firefox or IE, and while Microsoft has its monthly patch day tomorrow, I wouldn’t expect this to show up quite that soon.

OK, chalk this one up in the “What the heck?” column:

The limitation of the Photon Hypothesis

According to the electromagnetic theory of light, its energy is related to the amplitude of the electric field of the electromagnetic wave, W=eE^2(where E is the amplitude). It apparently has nothing to do with the light’s circular frequency v.

To explain the photoelectric effect, Einstein put forward the photon hypothesis. His paper hypothesized light was made of quantum packets of energy called photons. Each photon carried a specific energy related to its circular frequency v, E=hv. This has nothing to do with the amplitude of the electromagnetic wave.

And so on. It triggered a number of spam tests, including forged headers, a failed SPF check, and appearances in both Razor and DCC, which means a lot of other people got the same mail. It’s plain text, no attachments, and the only link in the message is to a physics site. As near as I can tell, someone’s just randomly sending out a physics paper by email. That leads to the question: why?
