The most attractive mail lists for me are ones that always modify messages, namely removing the mountain of HTML and leaving just the text/plain. I wish that all WG Chairs exercised that option. Only today, on another list, I saw a well-respected contributor say "Oh, how I hate HTML emails!" Yes. I note too that e-mails in unusual dialects appear to get footers added in text/plain, to identify which list they are on. I believe that this does not invalid the origin DKIM signature, so I see the criterion as always modifying messages but not in a way that invalids DKIM signatures. Tom Petch > Viktor. >
