Default postfix can not send to a hotmail account

Hello

I have been following this tutorial: "The Perfect Server Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]"

Everything works fine except when I try to send mails to a hotmail account. I get this fault repport: (I use of course postfix)

I understand that it is something with Id-sender, but nothing more but that. Does somebody knows what i have to do?
