problems.)
Or in short: DMARC intentionally breaks every mailinglist and every
mail-forwardi
Google groups replace the from: with their group address. What I know the big
providers having strict DMARC setting are:
mail.ru
laposte.net
I am glad the more large providers like gmail, outlook don’t have this stupid
setting.

I have never seen it and I'm subscribed to many Google-based mailing lists.
They replace the envelope from address (like almost every mailing list
server does), but keep the original Fro
Hello
if you have used a mail.ru email for google groups, when you posted message to
group, it will replace From header with the list address.

I totally agreed with you @Rafa.

Does it re-sign the message then? Because replacing the From: header would
break DKIM, as this header

There is a DNSBL maintained by bit.nl that allows you to block countries

Thanks for the reply.
Yes, I need smtp_sender_dependent_authentication because the upstream
