Thanks for the patch, Steve.  I'm not sure yet which way we're headed, 
and I believe any solution requires changing our whole DKIM setup (to 
let Sympa do it, instead of Postfix/OpenDKIM).  But it also looks like 
we're all going to have to do *something*, because Yahoo isn't going to 
back down, and that probably means all other big providers will go the 
same way soon:

Sympa team, it appears Sympa must somehow incorporate DMARC compliance. 
 I don't think we've seen anything from you yet about this topic, so 
can you please let us know you're taking it seriously?
