When I'm trying to send the first time the email notification for the account creation to for example gmail address, I get the message in the exim logs that the email couldn't be delivered due to the DMARC policy that is active for my hosting domain "mydomain.be".

When doing a password reset the email is sent and received correctly.

The main difference I see in the exim logs is the first time it's just like a command /usr/sbin/sendmail -t and second time it's like /usr/sbin/sendmail -t -f "admin <[email protected]>"
So is this something which should be improved or is it something we can control ourself?
