It's because the mailing list sends as "From: original sender address". Boost's mail server is not an allowed sender of "@Microsoft.com" mail so this gets triggered.

Hi,
Why is this message in Spam? It has a from address in microsoft.com but has failed microsoft.com's required tests for authentication. Learn more
I think this list isn't configured properly.. and this causes some messages to end up in Spam consistently.. Who's responsible for the mailing list infrastructure?
