Marcus, I'd be willing to offer up my server for use as an SMTP relay, after getting a bit of understanding of the current mail stream and its reputation. I'm running a server doing very similar things to yours, and I generally don't have any Microsoft issues (today, anyway). Combining good mail streams together is a potential mitigation against future issues, as well. Feel free to reach out, if you are interested and would like to discuss.
