[syslinux] DMARC Considerations

[Shao Miller]

Maybe this[1] page, option 3.C.  That strikes me as attractive, if only 
the mailing-list software can easily support it.  (Or be hacked to 
support it; I'm willing to try.)

Or, the "From" could be the mailing-list, the "Reply-To" could be the 
author, then the "CC" could be the mailing-list plus original "CC" 
addresses.  If someone hits the "Reply" button on their key-panel, they 
reach the author.  If someone hits "Reply All", the mailing-list also 
grabs it.  If someone hits "Reply List", it's because their e-mail 
program is smart like that.

Ultimately, I don't think counter-measures against spoofing "From" are 
going away any time soon.
