We have filled out the form Microsoft has for this case several times, getting automatic answers, but no help. This is the form:
https://support.msn.com/eform.aspx?productKey=edfsmsbl&ct=eformts
The technical standards have been reviewed and checked. Also we have implemented SPF and DomainKeys in order to comply with their policies.

Also we have sign up for the JMRP (Junk Mail Reporting Program) and the Smart Network Data Services. At SNDS we have ckecked that we didn't send any spam (from our IP range) in the last 72 days (It shows you just the last 70 days only).
After checking everything and implementing SPF and DomainKeys we have filled out all the forms again. No luck.
Hotmail keeps sending us the same link to their directives, the same form and not a clue about the problem.
We are a honest company, we don't send spam and we are going to end business if we don't solve this as soon as possible because our client's contacts are 70% hotmail users and they can't conttact them.
Can you please help us?
Thanks.
