There are currently no OS X DeltaSync-based clients, however you could consider building a solution based on jdeltasync. Of course, this may be reasonable because, amongst other reasons, all of your contacts have the email address, you're comfortable with how it works, etc.

The basis of your question rests on the fact that you're not willing to relinquish your hotmail account. Is it really that hard to get Hotmail working in Mac? I am willing to pay for a solution and I just can't find such a software! I am also willing to pay a one-time fee for an IMAP gateway too and I can't find any such thing either. Information to a POP3 clients flows one way so the Mac cannot update the server with read status, reply status and more. I just want a mail client that truly syncs with Hotmail. Mac's Mail program works with many Exchange servers, so I am really confused why Mac Mail cannot ActiveSync with my Hotmail account which apparently supports Exchange. Hotmail used Exchange ActiveSync which works well on my iPhone.

I looked at IzyMail but I am not willing to pay a subscription - I don't mind paying a one time fee though. In anycase, mBox has been out of development since 2009. I tried mBox for Mac and it worked great for about 2 weeks and now it stopped working with the new Lion Mail.app update.

The Mail.app only supports POP3 for Hotmail which I hate because it is only local sync - I am looking for either IMAP/DeltaSync/Exchange (i.e. I have tried that numerous times - Gmail fails at importing filter rules or nested folders properly from Hotmail and it also has numerous issues with sync and contacts etc when importing from Hotmail. Also, don't ask me to forward/import to Gmail. don't ask me to switch - have hundreds of filters and folders and thousands of contacts) and I recently switched to a Mac and I am looking for a Mac client that would deliver the same functionality as Windows Live Mail did in my PC. I have had an Hotmail account since 1997 (i.e.
