You have no SPF record on bitcoin-24.com, and most likely no DKIM either. These are good first steps.

set the SPF record, but it does not help. will take a look at DKIM –  DjangoSi Mar 12 '13 at 14:37
    
It does help, spam's just a multi-factor situation. The more anti-spam things you implement, the better. –  ceejayoz Mar 12 '13 at 14:40
    
Have now SPF and DKIM running, but the emails does not pass trough hotmail :( - take a look at the update –  DjangoSi Mar 12 '13 at 20:43
    
Try sending more legitimate-looking e-mail than a subject of "test". Content analysis plays a role, too. Hotmail is notoriously strict on inbound e-mail. –  ceejayoz Mar 12 '13 at 20:45
    
tried again but does not work. I think that the hotmail spam filter is very bad! Just saw that the account of my girlfriend have a lot of spam mails from serious companies, which are not spam –  DjangoSi Mar 12 '13 at 20:55

Your forward and reverse DNS match. This is good.

Your mailname (mail.bitcoin-24.com) doesn't match the reverse DNS. This may not matter much as the forward lookup for that domain does match.

Your reputation is fine.

Implementing DKIM, SPF and DMARC may help delivery. Hitting the "Not junk" button in Hotmail might too.
