I just learned that using a ARM64 CPU instead of a x86 CPU (32 or 64-Bit) will reduce the Energy coast of Server extremely (CPU Energy manufacturing costs and Runtime Operation Energy costs).

According other sources cows will be responsible for 80% of the co2 production in the future. Go vegan and pump your bicycle and you will have a clean conscience.

I believe back in the old days burning witches also had an impact on climate change. Good thing we don't do that anymore.
Now we only have to deal with politicians letting out co2 every time they open their mouths.

There are no false-positives on lashback, the IP's are not reported by anyone. I get that. I read the same thing when i started using it. But that doesn't matter.

The logical flow should be to disregard "Require SMTP authentication" if "Allow deliveries from" is unselected.

I have not yet looked in the code (other than I found Martin can't spell "deliveries") but it's somewhere in the SMTP logic. The priority of option checking needs to be altered.

Got another false positive from lashback: bona fide message from uber eats (food delivery receipt). X-hMailServer-Reason-1: Rejected by LashBack - (Score: 3) It was scored, not rejected.
