Re: Procured kit needs regulating too.
It probably is, because otherwise you have yet more hardware to maintain. And everyone can run Windows.

You should always have enough food, water, and a way to stay warm, for a couple of weeks at least. If there's a source of fresh water nearby having a Berkey in your emergency kit is advisable. Most of us are carrying enough body fat to live for weeks or even months without much food, but clean water is essential.
DMARC works fine for forwarded messages as long as you don't alter them in transit (assuming they were DKIM-signed, SPF obviously is not suitable for use).
Mailing lists can choose to either not modify the message or they should remove auth headers and replace From: with their own address to take responsibility for sending an altered message.
It's not pointless.
Your data - ie, the details of everything you do on or near your computer, is worth more to Microsoft and other big-tech companies than what you paid for Windows. Afaik Apple is the only big-tech company that hasn't completely embraced that model, at least on the PC front (mobile being another story of course).
Your TV does it. Even your effing car does it now. You and your behaviours are just products to be sold to advertisers, and who knows who else. Amazon is buying Roomba so they can get access to the maps and images of contents of everyone's homes (sad, I used to like my Roomba). So they can sell you more crap.
It's completely unreal.
SPF does nothing cryptographically. You're thinking DKIM, which adds a signature.
Neither actually authenticates an email or says anything about whether it is spam or not. Spammers use SPF and DKIM too. Especially the main-sleeze marketers this article is talking about.
Combined with DMARC and aligned identifiers, SPF and DKIM do make it easier to whitelist some senders and identify From: address forgeries, though.
So imagine you're a customer service agent at Network Solutions.
100 times a day clueless domain owners phone you and tell you they forgot their password or for whatever other reason can't get into their accounts or change their information.
99.999% of the time it turns out they're real and just need help.
How do you as a customer service agent reliably identify the one time they aren't?
Samba 4+ can run as full AD directory servers or members. Windows administration tools work on them.
I wouldn't necessarily recommend it for an SMB, but if you have anyone in ops who actually knows how to run Linux it's quite possible to fully implement an AD server infrastructure using just Samba.
