[RCU] This appears to be the problem I am getting with this list - and now other lists - DMARC / DKIM / SPF

Yeah, not much has changed since I wrote that except that even more
domains have published inappropriately strict DMARC policies.

>so stop dkim sign a maillists, but do the arc signing / seal

Sorry, that's wrong. ARC seals are a good idea (not very effective yet
but we can hope), but they're useless unless the list signs, too.

Since Roundcube doesn't run mailing lists further questions would
better be sent to lists about Mailman or Sympa or whatever really does
run your mailing lists.

R's,
