Hello, If this works at all. I just send a regular reply and got "<netfilter@xxxxxxxxxxxxxxx>: host smtp.subspace.kernel.org[44.238.234.78] said: 550 5.7.1 Your message looked spammy to us. Please check https://subspace.kernel.org/etiquette.html and resend. (in reply to end of DATA command)" Nice. I am not going to try to jump through your hoops which is mostly fruitless. So I register kernel.org as unreachable. That means, no feedback on the bug reports I submitted. But then, I presume this e-mail will be rejected as well.
