The FBI obtained this information through a Mutual Legal Assistance Treaty request on January 25, 2024, identifying the activist behind the anonymous account through their credit card identifier.

Just set up dkim, SPF, and dmarc properly and you should be good.

    Nope. Take for example Gmx.

    Due to the heuristics some of the providers have, such as Microsoft, they will start classifying mail sent from gmx as spam and auto move it to people's spam folder. They have developed their own internal trust metrics and these periodically just spambin low trust servers

    I can't say either way, I manage dozens of M365 tenants myself and usually what trips it is lack of SPF/dkim/dmarc or bulk senders. But again, not common to have independent mail providers these days but even Microsoft still makes Microsoft exchange server...
