smtp email not delivered to Hotmail

Our website www.ucubd.com is installed on a windows 2003 server.  The website allows users to send email from the website using smtp email.  The email used in sending the smtp email is ucubd@ucubd.com.  Our hosting company maintains our company email on another server. That email also uses the ucubd.com domain.  We are able successfully send smtp email from the site to major email providers suchs gmail, yahoo mail, godaddy mail.  Unfortunately Hotmail is not letting our smtp email go through.  There are no errors or bouncebacks, the email never ends up in a Hotmail inbox or spam folder.
What can be done to resolve this? Is there a way to contact Microsoft Hotmail about that? How can I get whitelisted with Hotmail?

Thank you for your help.

Hi Maratq
I just recently had the same issue. Here is the information i found and followed, to get unblocked.

Hotmail is very strict with spam complaints and they DO NOT bounce emails. They only filter to trash or junk mail. If they get only a few they will filter all email from your account. They will also filter if they detect you are sending to many non-existent accounts, since this is a characteristic of spammers.

If you use your own domain name as your FROM EMAIL ADDRESS, you can set up SPF records under your domain that will improve delivery to Hotmail. Hotmail uses senderID to accept mail and require that you set up spf records on the domain you use for your FROM email address. You will need to contact your host and ask them if they publish SPF records and are compatible with Microsoft's Sender ID initiative. Unfortunately, this is the only way to ensure delivery to Hotmail due to Hotmail's policies.

Once you have set up spf records, let Hotmail know by sending them an email at senderid@microsoft.com with your domain name in the body. We will then configure your StreamSend account accordingly.

If you are not sending from your own domain, our only recommendation is that you wait 48 hours or more between sends. Hotmail may remove your account from their filtering if they do not receive complaints within a certain span of time.

I've had my hosting company publish the SPF record.  However, our emails are still not getting through to Hotmail.  Is there anything else I can do?
