I would really appreciate if somebody could help me with an issue I am facing with my MiaB setup. Basically I use it to receive and send regular email but also to send out marketing campaigns via another server. The problem is that all emails end up in spam as they are sent out from Sendy which in turn is configured to send emails via Amazon SES. I have used an email testing website and the only thing that it says is that my server fails DMARC verification. I have added the Amazon SES DMARC CNAME records to MiaB custom DNS settings but the problem is that the verification process fails. I know this is a bit more on advanced side but I am curious why does the Amazon SES fail to verify the DMARC records despite them being correct? Is there something that keeps it from verifying?
