When you click the message in Spam folder, Gmail displays a banner which gives you a clue why the message was marked as spam. The reason can be one of many:
Many people indicated similar message as spam. It's similar to messages that were detected by our spam filters. Messages from domain.tld are considered spam. Try to send different messages in your tests. Not Suject: test, body: test. In hotmail, view source, you have x-message-delivery: base64-key. Decode that base64 key and see the SCL score. Above 4 is bad. Also, hotmail provides a reason why the message was delivered to Spam folder: you are not interested or the SmartScreen detected as spam. Check your IP and domain in multirbl.valli.org Marius.

What I did I replaced the mail system. The orginal was postfix 2.5.5, the new is 2.11.0. Thanks for the idea of DKIM I will look the detail and I also continue search for the archives.

When you start sending from a "new" IP address, it is not unusual for the big email providers to "spam" your mail initially, until they get an idea of what's coming from your server and know that they can trust it. You should also sign your emails with DKIM. I have seen that make the different between going to spam and not. As Christian says, this has been discussed before, so worth searching the archives.
