hotmail users can't receive any email sending from postfix

Recently, I setup a postfix mail server version 2.2.10 , however I found
that hotmail drop all emails silently sending from my postfix server.

I look into the mail log and found it sent sucessfully without any email
bounce or rejection error log

Here it is the log
Aug 14 17:43:39 dmhy postfix/pickup[1934]: 9D72028C1E7: uid=99 from=<nobody>
Aug 14 17:43:39 dmhy postfix/cleanup[3141]: 9D72028C1E7: message-id=<

mail.example.com>, size=450, nrcpt=1 (queue active)

relay=mx3.hotmail.com[65.54.244.72], delay=1, status=sent (250 <
20060814094339.9D72028C1E7mail.example.com> Queued mail for delivery)
Aug 14 17:43:40 dmhy postfix/qmgr[14423]: 9D72028C1E7: removed

for security reason I replaced all real address and domain by foo email
address and domain.
Back to the mail log, mail seems send sucessfull.

I heard that hotmail has very restrictive configuration and rules to handle
spam email. And smtp server need special configuration to handle hotmail
address

I'm not sure this is my case.
