I do. There are now projects giving you all the required tools in a single easy package. I use stalwart mail server as it includes all the relevant functions that I would have to host separately with other solutions. (CalDAV, CardDAV, DMARC Reporting, DANE, MTA-STS, Rate Limiting, Authentication, Spam Filtering etc.). Also facilitated by having a ISP which gives me fixed IPv6 addresses for free and a fixed IPv4 for a reasonable price. I additionally host simplelogin myself for managing aliases I use for logins.

I now get a lot less spam, I think the unsolicited senders mostly concentrate on the big mailhosters.

So they're going to deliver sysmon.exe as a windows optional feature. There's nothing native to it. No config management via GPO or CSP or similar. Nothing. Just replacing the scheduled task/powershell script downloading exe and config by one enabling the feature and downloading the config.

They want devs to choose Windows so they develop the next big AI app on Windows to draw the gullible users to Windows. Would be a shame if they choose macOS or even Linux instead.

The downgrade was implemented by the operator of the application. The phishers only found a way to exploit the downgrade.

A GWy is 8760 GWh. Cost for nuclear is about 100 USD/MWh So about 876M USD for 5000kg Gold worth 536M USD. This is only for the energy, no raw materials and apparatus.

Unfortunately many people don't like to think themselves (not that AI would do it).

You can set the minimum extrusion width to a small value (20-25%) for better fill. You could also use classic mode with gap fill. You can use ironing for both to improve the results.

Does your slicer have Arachne slicing mode? It will use variable extrusion width which will help to prevent most of those gaps.

Ah yes. But you can just reject NDR messages with "550 5.7.509: Access denied, sending domain example.net does not pass DMARC verification and has a DMARC policy of reject" now.

Yes, however RFC7208 says not to send NDR when sender authentication fails (=when SPF/DMARC is correctly set up it will fail) So you will get massively less backscatter. There will still be some providers sending NDRs however not the big ones, they will instead inform you via DMARC reporting which is easier to ignore.

Generating non-delivery notifications to forged identities that have
   failed the authorization check often constitutes backscatter, i.e.,
   nuisance rejection notices that are not actionable.  Operators are
   strongly advised to avoid such practices

You want DMARC to protect the header From. This will protect you from backscatter due to out of office replies etc. Bounces go to the envelope from and are due to rejected mails.

TL;DR Implement SPF to not get bounces and implement DMARC to not get backscatter.
