That's the old mailman2 archives, that are now really only an archive, 
no new mails appear there anymore.

mailman3 has hyperkitty and public-inbox for archives.

I never got such a Mail, and it's also not in the archives:
https://lists.ffmpeg.org/lore/ffmpeg-devel/?q=fftools%2Fopt_common%3A+add+separator+line+to+show_filters+output

So something has likely gone wrong with it.
