I know I am a tiny speck, but as just another data point, I'm looking
at a folder full of spam with 731 messages in it, received here since
May 15, 367 (almost exactly 50%) of which originated at GMail, 45 via
outlook.com, 25 via salesforce.com and 16 via sendgrid.net. Of those
367 sent via GMail, 57 are bogus billing notices for "Windows
Defender", which I've since had to write custom sendmail filtering
rules to block. They were coming in at a rate that made it such that I
could test the rules in the half an hour I spent writing them because,
lo, there's another one.

Most of the rest are either blindingly obvious 419 scams or offers to
help us estimate our construction projects, give us a better web site
or improve our SEO. The latter I can deal with, they're just cold call
campaigns, and hey, everybody has to eat, but the Defender phishes are
just stupid and someone should have stopped them months ago. How hard
is it to flag a campaign whose sender is "Windows Defender Order" and
Subject is "Order Confirmation" or "Billing Team" without variation?

Aside from a few whitelisted addresses, we quarantine everything sent
via GMail here, to save our users the hassle of having to forward them
to me and file them away for reference in posts like this.
