Qmail not delivering to Hotmail

Hi All
I have Qmail on a dedicated server it is delivering emails to yahoo "with delay" and gmail, however it is not delivering to hotmail. I do have the MX records and SPF setup correctly

From my gmail email
Received-SPF: pass
Authentication-Results: mx.google.com; spf=pass

There are no bounces or anything significant in the logs. It is as if hotmail swallows those emails.

Any help ?

Have you checked to see if you are black-listed by any of the SPAM catogorizing agency.  Hotmail could be using a different spam filter other than yahoo or google resulting in the messages being swallowed.

Send a test email from the server to sa-test@sendmail.net and it will respond with an analysis of a number of spam preventing elements of your email.

For example, it returns the following analysis to me after receiving an email from one of our servers (note, I only have DomainKeys set up and NOT DKIM):

Authentication System:       DomainKeys Identified Mail
   Result:                   (no result present)
   Reporting host:                              
   More information:         http://mipassoc.org/dkim/
   Sendmail milter:          https://sourceforge.net/projects/dkim-milter/

Authentication System:       Domain Keys        
   Result:                   DK signature confirmed GOOD
   Description:              Signature verified, message arrived intact
   Reporting host:           sendmail.net        
   More information:         http://antispam.yahoo.com/domainkeys
   Sendmail milter:          https://sourceforge.net/projects/domainkeys-milter/

Authentication System:       Sender ID          
   Result:                   SID data confirmed GOOD
   Description:              Sending host is authorized for sending domain
   Reporting host:           sendmail.net        
   More information:         http://www.microsoft.com/senderid
   Sendmail milter:          https://sourceforge.net/projects/sid-milter/

Authentication System:       Sender Permitted From (SPF)
   Result:                   SPF data confirmed GOOD
   Description:              Sending host is authorized for sending domain
   Reporting host:           sendmail.net        
   More information:         http://spf.pobox.com/

I'd recommend ensuring that DomainKeys is set up on the system in question too:

Hmm...Sender ID ...SPF and domain keys are implemented.

To my knowledge, SenderID is heavily relied upon by Microsoft.
