i have found a solution for the problem, but it only works with the mail app not with the iphone.
i got my very own name@name.com email adress which i forward to my new mobile me account. then in the mail app i added my name@name.com account but deactivated it (this is needed for the smtp server). i now added name@name.com as additional reply email adress in the same line with name@me.com, name@mac.com.
i now receive all my mail via push and can reply with whatever adress i want to.
