dovecot - Jun 2021 - Dovecot mailing list and DKIM

No yahoo specific problem, as I stated in my previous post.
An yes, my DKIM record validates successfully.

But there are a couple of messages sent from other users, through the 
Dovecot mailing list, that fail DKIM validation, like the one in the 
example link.

I am just curious why do the vast majority pass while some fail, even if 
they do have proper DKIM records :) .

Cheers.

if ARC specifikation tells more about C= tag in dkim, it would be more 
easy to see if its just that, relaxed is more simple to make dkim pass 
with then simple is, there might be alot of other problems giving random 
pass or fails, i just say its not possible to garenti that mail in 
transfer on public maillists or stupid sendgrid forwards with phishing 
netflix emails, it can only be trusted if ARC is done on any forwarders

i am glad i do not use any milters currently since gentoo have disabled 
milter support in postfix

so currently i am happy with fuglu :=)
