look at this replay from hotmail i receive it before more than 2 week ago :
Thank you for writing to Sender ID Management Team. My name is Chynna and it is my understanding that your SPF is ok. You want to know where the issue lies. I am glad to be of assistance.
I rechecked your domain and I have added your XXXX.com domain to the Sender ID program. This may take up to 2 business days to be fully replicated in our systems. If you have any questions regarding this please let me know.
If you should make any changes to your SPF record, you do not need to notify us when you make this or any revision to your SPF record since we will automatically pull the current record from the DNS daily.
Thanks again for your support in improving online trust and confidence. Have a great day ahead.
Sender ID Management Team
