Microsoft Fights Spam at the Source

In its continuing fight against unsolicited commercial e-mail, Microsoft plans to filter outgoing messages on its consumer mail services and is busy developing new "proofing" technologies, the software maker's chief spam fighter says. The fight is also one against the clock. Microsoft last year set a two-year goal to make spam a problem of the past. There are 19 months left, says Ryan Hamlin, general manager of Microsoft's Security Technology & Strategy group, speaking at this week's INBOX, a conference on e-mail in San Jose, California.

More than 14.5 billion spam messages are sent each day, according to Hamlin, who cites figures from antispam vendor Brightmail. Microsoft's Hotmail Web-based e-mail service receives 2.7 billion spam messages a day, Hamlin says. As part of its efforts to stop spam, Microsoft in the coming months plans to apply spam filters not only to incoming mail on its Hotmail and MSN services, but also to outbound mail. The filtering will kick in when users send a large number of messages and is intended to help stop abuse of Microsoft's services by senders of spam, Hamlin says. He called out to ISPs and other e-mail service providers to do the same. "All of the ISPs and large senders of mail need to be filtering on the outbound side," he says. "There is a lot of abuse happening. We need to have better outbound filtering to look for people that are abusing our systems."

The primary ISPs that deliver the bulk of spam are not going to listen.

Most spammers hop from ISP to ISP I imagine.

it isn't people that are spamming though - its mainly comprimised computers. why the hell would you use hotmail to send spam anyway, its probably the slowest e-mail service out there, and certainly the least useful (without pop3/smtp) for sending large amounts of emails.

yeah they are pretty awful as the storage limit is a pathetic 2Mb, it inst too slow but it is incredibly useless. i suppose its good in a way because u need the .net passport to access help from microsoft and u can use messenger with- again another source of SPAM which is SPIM.

No i dont think people use hotmail to spam anyway unless they spoof IP addresses. If you get spam from a @hotmail.com address yes it is probably spoofed also.

Good point. MSN Hotmail also limits the number of emails any individual free account can send per day. The actual limit isn't public knowledge...but the average free hotmail user shouldn't run up against the limit unless they are spamming.

Hmmm, not too many tech-savvy readers on this topic, eh?

Consider:

Point 1: Jumping from ISP to ISP is only a stop-gap measure. The big four have already gotten together, and are already putting *******s in jail. It's only a matter of time before the vast majority of ISP's also get into the act, and drive the clowns outta bizness.

Point 2: Filtering on the outgoing stream isn't only for counting the number of pieces sent by one account-holder, it's for counting the number of very similar or exact same pieces from all account-holders. Spoofing isn't reserved to IP addys, it's also possible to spoof account-holder names. Also, it helps to see if large numbers of the same thing are coming from another server, asking your server to relay them.

Point 3: A server (MSN/Hotmail) doesn't have to be fast to send spam. Even the slowest message will still arrive at an inbox, and piss off the recipient!

Point 4: A compromised computer is only relaying the spam, it didn't originate the crap. (But see my next point on what to do about this.)

Point 5: People who let their personal 'puters relay spam outta be shot at sunrise, or at least lose their computing privileges until they're 80 years old. By then they'll be mature enough to understand their responsibilities to other people on the 'Net.

The *******s who originate spam should not be put to death - they should be made to sit on the county courthouse steps and read their messages. All the way through. Out loud. In front of the public. Each and every piece of spam they sent. All 3.8 million of 'em.

When they're done, then they can go home (which outta be sometime around 2065 or so).
