Did you check any of the points in:
* Messages must not be transmitted through insecure email relay or proxy servers.
* Connections from dynamic IP space may not be accepted.
* Email servers must have valid reverse DNS records.
Is your email server "mail.myurl.com" set up correctly? Does it have a valid reverse DNS record? Does it have a static IP address?
You are sending the message with SSL disabled -- this might be sufficient for Hotmail to decide the email is insecure and route it to the spam folder.
Have you tried sending the exact same email message from a standard email client?
That way you can differentiate between problems with the content of the message and problems with the way it is being sent.
Hotmail may decide that short messages with links in them are spam unless they come from people in the recepients address book. (That's a pretty reasonable assumption.)
