Well, it was fun while it lasted, but Microsoft has finally decided to close access to its servers via the WebDav (or HttpMail) protocol. As my hotmail plugin uses this protocol to communicate with the hotmail servers this means that as of June 30th 2008 my plugin will no longer work
I am looking into their new protocol called DeltaSync, but from what I can see Microsoft is using some proprietry encryption/compression on message contents, so it might take a little while (if ever) for it to see the light of day.
Thanks to everyone for all the donations and support over the last 5 years or so.
If I manage to figure out the compression then a new plugin supporting Windows Live mail should be fairly easy to create. Ill post progress here if there is any
