People,
FYI, this seems to explain (most of) my hassles mailing to this list:
Yahoo breaks every mailing list in the world including the IETF's
https://mailarchive.ietf.org/arch/msg/ietf/J-IsfA0Lb-6T_NeMD1ENKZyb9tA/
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
