Hi all who is can help me? I want create email login: Yahoo mail, Hotmail, Gmail, AOL, GMX for post data login with AJAX the result is directcly open as in to the each mail.

JavaScript isn't allowed to make AJAX requests to outside websites, for security reasons, but it may be possible to do another way. Read about AJAX file uploads, as they don't actually use the XML HTTP request object, and instead post data by targeting a hidden iframe. If you find out where the post data is going in each case, you may be able to do something similar.

You may also want to check to see if Gmail and Yahoo mail offer an API that will allow you to do this in another way.
