    You can spam from hotmail without using the web-client, since it has an interface for using /w outlook etc (http mail still though I think).
    However, I myself don't get many *hotmail* spams, and many which I do are forged headers and not real hotmail addresses.

    Limiting regular customers to emails-per-day actually sounds like a really good idea to me, so long customers sending mass mail (usergroups, proper mailing lists, etc) were able to sign up for a "special account" allowing them to continue. I don't know many normal people who would send >200 messages a day, and not many spammers who might bother to identify themselves when signing up for a special "mass-mail" account.

    The last time I posted this question, it was late in the discussion and didn't get many responses. So I'll ask again. Does anyone here have any experiences with Disposable Email Address services? Click the above link to get a more detailed explanation of what it is.
    Briefly, I'll explain how they work in theory. After signing up with a disposable email service, they give you a disposable email address that you can, for example, enter into forms. Mail sent to that disposable email address gets automatically forwarded to your email account of choice. But here's where they supposedly come in handy. You can sign up for a different disposable email address everytime you fill in a web form. If you start getting spam, you can look at the disposable email address the spam was sent to and you can do 2 things: (1) cancel the disposable email address so you no longer get spam sent to that address; and (2) you know who gave out your disposable address and you can take whatever action you deem appropriate.

    To offer the system for email requires a more advanced server-client architecture, overcoming challenges such as "what if both systems require authentication" to ensure that Spam still can not get through a 'hole' for this scenario, and finally: The actual challenge-response is being done wrong by almost all of our competitors. A simple dictionary attack could authenticate a spammer for their entire user list.

    We're the longest running email-authentication project (obviously, since we did invent it) and we have a very large list of improvements planned for the system.

The spammer has hijacked your box and used it to send quickie text messages to 3rd parties.

  17. Cringely has an interesting proposal by Norman+Lorrain · · Score: 2, Interesting
    in this week's pulpit.

    Basically, it's challenge/response, with the response being via telephone

    I replied to him with the following:

    I like your idea, I think it'll work. It's a variation of the challenge/response scheme, with the response being via a sender-paid phone call.

    Here's a story: 2 years ago, we moved, so I had to change ISPs. I took the opportunity to do an experiment - my new email address I only divulge to people I know; everything else I use a Hotmail account for. In 2 years I have NEVER received spam on my "private" account, and I don't even have a filter enabled. Hotmail, on the other hand, is a different story, but is handy for internet purchases and emailing pundits.

    Some points to ponder

    - Your forum is a good way to get the ball rolling. Once a reasonable scheme is agreed upon, you could post it (maybe as an RFC) and the practice could spread virus-like from there. Even post instructions for Outlook users (rules wizard). If this catches on, a setup.exe for this filter would be a hot download!

    - When subscribing to mailing lists, one might forget to add the address to your address book, thereby flooding the list with the "challenge" email. There should be a standard tag in the challenge that mailing list servers can filter on, and even automatically take you off the list.

    - Since an auto-reply confirms to the spammer the address, the filter should ALWAYS delete the email. Once this practice is known, this might even prompt spammers to take you *off* his list. Saving the message would lead some spammers to continue on the off chance you might look through your spam folder later on.

    - Using this scheme with bob@cringely.com obviously is not going to work (if you posted a controversial article, it would give new meaning to "slashdotting"). However few email users have a web site that invites comments. If a spammer loses a large percentage of his address list, he'll close up shop completely (here's a question: what is that percentage? How many email addresses make spamming a worthwhile income generator?)

    - Registering with sites like NYtimes.com should be done with a disposable address, because forgetting the password requires an email be sent from some unknowable sender (forgot@lga2.nytimes.com)

    So that's the new email reality. Get a private address equipped with the challenge/telephone response. Get a disposable address for shopping, or reading the news. And backup your address book.

    Sample template for the challenge message:

    I don't know who you are. If you want me to read your message, call me at xxx-xxx-xxxx and we can arrange to allow future messages to come straight through.

    The message you sent was automatically deleted. I did not see it. Sorry for the inconvenience.

    <SPAM CHALLENGE> this tag is for mail list managers </SPAM CHALLENGE>

    As some else pointed out, the filter should check addresses that have had messages sent to, to avoid challenge/response infinite loops.

    The spammers will just build an automated response system. Plus, this thing could no be used as a source for a DOS attack, since its happily generating emails. And god help us if they ever decide they need to sell their "contact list to be profitable, since to work it must have a list of every person who might email you. And hopefully they've considered the feed back loop as service A asks for a confirmation of the confirmation email service B just asked for... :^)

    Yeah, I think I'll give this a pass

    Curiously, why were open relays ever in existence? And once spam started, why were open relays kept around? Is there a use for them? Why not have all mail servers require authentication for outgoing mail, much like POP retrieval. That would have to stop a great deal of spam

    Yes, it would. The idea is you send a single mail to the open relay with a huge list of recipients, the server then burns its bandwidth sending 900 copies of that mail. Not to mention it gets to deal with all the bounced emails messages, etc.

    So why do they exist?

    1) Best compatibility. Not everything understands how to authenticate SMTP.

    2) Firewall compatibility. Some firewalls don't allow authenticated SMTP in more secure modes

    3) Traveling clients. If your client could concievably pop up at any IP, its very difficult to filter access by IP, the usual method of blocking unauthorized access

    4) Don't fix what aint broke. If its working, some folks are hesitant to make changes they aren't comfortable with.

    5) A workaround opened a previously closed relay. Spammers have gotten tricky in fooling Mail relays into forwarding their spam. there's a lot of ope relays that were closed when originally set up.

    6) Philosphical reasons. Folks may wish to provide a service that bypasses listening in by corporations or governments
