Is It Time To Setup A 'don't Use Hotmail Advisory Website'

Hotmail doesn't work. The email filtering technologies are still broken 18 months after the original problems were found with their implementation. And now it looks like they've stopped supporting it.

Seriously, does anyone know if the email filtering team at Microsoft has just given up on responding to requests and complaints? We've just deployed two new servers and both are blocked for delivering email to clients Hotmail/MSN/Live.com accounts.

The following steps have been taken:

1. Our DNS has been tested and checked using DNSstuff.com services.

2. Our server IP addresses checked to ensure they do not appear in any blacklists.

3. rDNS correctly setup for hostnames and mailserver names.

4. All our email is signed using DomainKeys.

5. All our domain names have published SPF records.

6. All our domain names have valid abuse@ and postmaster@ email addresses.

7. We have emailed senderid@microsoft.com notifying them as requested on postmaster.msn.com of our published SPF records.

8. We have even completed the senderid support form providing further notification here:
[url]

9. I have contacted the technical support team using the contact form on [url] witn absolutely no success.

Two weeks later I've made no progress whatsoever beyond receiving a request to complete a survey rating the non-existent support I have received. (No human has responded to any of my messages) And all our messages to Hotmail are still disappearing into the email filtering black-hole.

At this point I'm starting to wonder if Hotmail is even usable as an email service anymore. I doubt many people will be bothering to jump through all the hoops I am to resolve this issue. I dread to think how much legitimate email is getting caught up in the Microsoft email filtering black-hole - never providing any notification or information to senders their messages were not delivered.

Meanwhile, our email arrives perfectly in Yahoo/Gmail who both pass our SPF records and DomainKeys signatures. Oh, and we're not engaging in any email marketing practises (i.e. spam).
