现在能够实现用js 登陆163邮箱，
switch (mailaddress) {
case "163":
{
var url = 'https://reg.163.com/logins.jsp?username=' + username + '@163.com&password=' + password + '&url=http://fm163.163.com/coremail/fcg/ntesdoor2'
window.open(url, null, "");
} break;
case "126":
{
var url = ？？; alert(url);
window.open(url, null, "");
} break;下面的126，雅虎。搜狐邮箱都找不到语句了，请大侠们给指点一下。
