Because right now your emails get marked as spam when you go through the kernel mailing list. Why? The kernel mailing list ends up rewriting white-space in the email headers, and you have DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=milek7.pl; s=dkim; .... where that "simple/simple" means that *any* change - even whitespace - will make DKIM fail. And quite frankly, "c=simple/simple" is just wrong. SMTP very much was never designed to care about whitespace in headers. The DKIM people were crazy to even allow and to codify that broken garbage. Yes, yes, the kernel mailing list should also be fixed to not do the header rewriting, but it is very fundamental to how it works (it simply doesn't save the headers as a collection of raw lines at all, it saves them as the cleaned-up thing). So it would involve switching everything around, and Davem just doesn't have the time and energy. And "c=simple/simple" really is bogus. So if at all possible, make the use milek7.pl DKIM setup use "c=relaxed/relaxed", and LKML will be happy again, and your emails don't get marked as spam.. Linus
