Is this (the > lack of a DKIM sig) the explanation to the problem with my mail [...] Are you aware of how DMARC works, in detail? DMARC relies on both DKIM and SPF. https://dmarcian.com/domain-checker/?domain=zoho.eu shows that the DMARC policy for this domain is "reject". Since you don't use DKIM signatures, it is down to only SPF, so if the SPF check fails, the DMARC policy applies. That means you ask the recipient MTA to reject all mail apparently originating at zoho.eu whenever the SPF check is unsuccessful. Adding DKIM to the mix is no silver bullet, but I personally would not publish DMARC policies "quarantine" or "reject" had I only SPF at my disposal! -Ralph
