Did they start unblocking SMTP on Azure? This hadn't crossed my desk
yet, but when I search for "cloudapp.azure.com" across my fleet I'm
immediately flooded with absolute junk. I grabbed a list of IPs from
just the most recent logs since rotation: https://clbin.com/z5D8t
The word "Bitcoin" is pretty prominent in the email subjects.

Spam started again about 10 minutes ago. The only sample I could look
at came through a forwarder, but I see IP level rejections for
cloudapp.azure.com.
Looks like Azure isn't able or willing to identify and stop the
spammer.
Cheers,
