Ahh, yes, I didn't even notice that you went through mail.kernel.org, I only noticed that loongson.cn did SPF but not DKIM. Yeah, if loongson had had DKIM and DMARC set up to match, it would have been an even noisier failure about DKIM actively failing, rather than not having DKIM at all. If you use mail.kernel.org, using a "From:" with a kernel.org address too to get the full email verification is likely the best option. That said, I went back and looked, and you've clearly been using this mail.kernel.org + loongson.cn model for a long time, and it hasn't been problematic. So your pull request being marked as spam might have been just a one-off. Linus
