Würde mich auch interessieren.
Ich habe ebenfalls Kontakt mit dem Support aufgenommen, und mir wurde dann letztendlich mitgeteilt dass der SmartScreen®-Filter dies automatisch rausfiltern würde und der Support da nichts weiter machen kann. Ich wurde nur darauf verwiesen, was ich möglicherweise alles machen könnte um die "Zustellbarkeit zu verbessern". Aber leider nichts konkretes.
Falls es noch jemanden interessiert, hier die originale Antwort vom Support: (private Daten wurden durch XXX ersetzt)
My name is XXX and I work with the Outlook.com Deliverability Support Team.
We have reviewed your IP(s) (XXX) and determined that messages are being filtered based on the recommendations of the SmartScreen® Filter.
Email filtering is based on many factors, but primarily it's due to mail content and recipient interaction with that mail. Because of the proprietary nature of SmartScreen® and because SmartScreen® Filter technology is always adapting and learning more about what is and isn't unwanted mail, it is not possible for us to offer specific advice about improving your mail content. However, in general SmartScreen® Filter evaluates specific words or characteristics from each e-mail message and weights them, based on their likelihood to indicate that a message is unwanted or legitimate mail.
Unfortunately, after reviewing the information you provided and in compliance with our mail policies, we are unable to offer immediate mitigation for your deliverability issue. However, we have some specific recommendations for you to consider that can help you to improve deliverability over time.
Here are some specific recommendations for you to consider:
Brand your mail
Ensure mails are cleanly formatted and clearly identifiable as originating from your service.
Follow content and formatting best practices
There are numerous Internet resources which offer advice and best practices, we recommend you refer to these resources for assistance creating well formatted and more deliverable email.
Highlight Opt In
Clearly mark your emails so that Windows Live Outlook.com customers are able to identify that they requested or subscribed to emails from your service.
Ensure your email lists are up to date
Remove those who do not want to receive the emails and consider making the unsubscribe process more visible to ensure you are only delivering mail to interested recipients.
Join the Junk Mail Reporting Program (JMRP)
We believe that your recipients are the best indicator that the email you are sending is wanted. The JMRP program allows you to see which of your emails Outlook.com users have marked as junk or unwanted mail. Reviewing the results in JMRP will provide to the most direct information on what characteristics of your email, customers, and ultimately SmartScreen®, consider to be unwanted. This helpful feedback mechanism allows you to ensure that mails being sent from your IP are not resulting in negative feedback that could impact your sending reputation. Being vigilant about users who mark your e-mail as unwanted or the types of messages that are being marked as unwanted can help you keep mailing lists updated with only interested users and modify future campaigns. In addition, monitoring user complaints can help you identify unintended mail traffic or detect a potentially compromised account sending unwanted mail to your customers. Enroll at https://postmaster.live.com/snds/JMRP.aspx?wa=wsignin1.0.
Join the Smart Network Data Services program (SNDS)
The SNDS program provides data about traffic seen originating from your registered IP, such as mail volume and complaint rates. The data is built from the log files of the inbound mail machines and other servers at Outlook.com and Microsoft and represents factual information about the traffic from your mail servers to Outlook.com users. For more information about this free program refer to https://postmaster.live.com/snds/FAQ.aspx. To register, please go to http://postmaster.msn.com/snds/. (Tip: As part of the enrollment process, you are asked to sign the JMRP program agreement and then send a response to Support indicating that it has been signed. It's not uncommon for that step in the enrollment process to be missed.)
We encourage you to take an active role in managing your email practices and infrastructure. The SmartScreen® filter is not static and it is possible to improve deliverability over time. Implementing and maintaining email best practices such as those described above can help.
We also encourage you to download and apply the industry best practices found in our Outlook.com Enhanced Deliverability white paper.

This mail outlines and refers to some best practices for sending to Outlook.com; however Microsoft makes no guarantees on delivery to Hotmail/Live/MSN/Outlook.com customers.
