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

maybe it breaks if maillists resign dkim or break dkim from original 
domains, sadly so is life with dkim today, there is maillists that only 
openARC seel all posts BEFORE breaking dkim sign, if that was done AFTER 
then openDMARC will see the break, but if its done before it will see 
original posters dkim pass and spf pass

sorry just saying

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

dovecot maillist have solved it, so can others
