How could I prevent my mail from being recognized as spam?
When sending legit large volume Emails from our IP (e.g. for sign up confirmation or Lost password) it gets marked as Junk in Hotmail.
In the past, there was the Sender ID SPF Record Submission Form, where you could put yourself on the radar of Microsoft. See this old discussion. However, as of April 2012 this has been abandoned.
Any hints what to do now? What is a good way to contact the Hotmail team?
