Windows Live compression update

I had a bit of time yesturday to spend working on the Windows Live compression reverse engineering.  I successfully decompressed around 20 bytes.  The previous record was 2 bytes 😉  There are two parts to the compression.  First is the compressed data and the second is pointers back into decompressed data.  The compressed data is working quite well, but the pointers to repeated blocks that have already been decompressed is off a little so I see some correct data and some rubbish.  Hopefully I’ll get some more time in the next couple of days to work on it some more.

  1. I didn’t quite understood all that you said, but it’s just too much fun to know all things HttpMail. 😛 Keep it up.

  2. Daniel-

    It seems that SAFARI 4 Beta does not play nicely with Windows Live. This means that for those of us using newer accounts that do not work with HTTPMAIL, we’re waiting! Can’t wait to hear news of your progress!

  3. Erm, is anyones HOTMAIL plugin just stopped working by any chance? It was all fine about 15 mins ago and now I can’t send or receive. I can’t get my account to go online. Odd!

  4. I definitivey agree with Regis,

    Just tried the POP3 live server on my Mac (10.5.7). Works perfectly!

    I’d like to thank Daniel for his amazing job that saved us time for so long!

  5. Dear Daniel,

    I’m using mac OS X 10.5.7 is there a plugging i can use so that i can use live mail on the mac’s mail app?


  6. Hey Daniel,

    Are you planning on making another plug in for hotmail that works with snow leopard?

  7. Hey Daniel,

    I stopped being able to retrieve my mail from my Hotmail account on my Mac yesterday. Here is the exact message I get “Connection Failure Could not connect to ‘Hotmail Account’Forbidden.” My internet access is fine and I didn’t touch anything as far as account settings go. Have you heard anything about this?


  8. Krista,

    I’m having the same problem as you had have found out that it is because hotmail has changed their formatting and is now allowing you to connect with POP even with free accounts. So I think this means that httpmail will be unnecessary and also not work. Daniel, can you confirm this?

    Also if this is indeed the case, what will it take to preserve all my hotmail messages that are saved in Mac Mail through httpmail when I switch to pop?

    Thanks so much.

  9. Yes. Same thing happened to me, and I’m confused as to what to do. Can someone spell out to me how to get my hotmail accounts back working on my mac mail? I have Mac OS X 10.4.11. I’m not as savvy with this stuff as y’all seem to be, so wondering if someone could be explicit. thank you thank you thank you

  10. Hey,

    i’m having the same problem with hotmail.

    I’ve found that they have realeased the POP.

    I’ve tried and work.

    Here’s what to do:

    POP server: (Port 995)
    POP SSL required? Yes
    User name: Your Windows Live ID, for example
    Password: The password you usually use to sign in to Hotmail or Windows Live
    SMTP server: (Port 25)
    Authentication required? Yes (this matches your POP username and password)
    TLS/SSL required? Yes

    Hope it works for you.


  11. Hey Daniel,
    It’s my understanding that Windows discontinued their httpmail protocol on Sept. 1, 2009, and now your beloved plugin doesn’t work on my mac anymore. Do you have a recent update? a fix? or do you recommend another application that will work with the new protocol and MacMail?

    Thanks for all your hard work and your great plugin!


  12. I had the same problem since 1st september.
    Now i changed all the settings (created new account inside Mail) to POP. and it works like a charm…..
    Thanks Luis for the tip….

  13. Hallo Daniel
    What is progress with DeltaSync email body encoding? Think i could even to pay for that some reasonable sum 😉
