I have SPF records and Sender-ID records set up for my domain:
v=spf1 -all
spf2.0/pra -all
The "" is for Office 365.

If I send an E-Mail to I get the following result:
SPF check:          pass
DomainKeys check:   neutral
DKIM check:         neutral
Sender-ID check:    pass
SpamAssassin check: ham
So I assume I have set the records up correctly. However when I send Mails to Hotmail they always get thrown in the Junk Mail folder.
I know that Microsoft does not search for Sender-ID entries in the live DNS system but they have their own cache. So I filled out the form at Microsoft and a few hours later got a response:
We have successfully added your domain to the Sender ID program.
Now, a few days later, it is still not working. Is there something I am missing? Here is the header of an E-Mail dropped by Hotmail:

Authentication-Results:; sender-id=temperror (sender IP is; dkim=none; x-hmca=none
