DMARC is the abbreviation for Domain-based Message Authentication Reporting & Conformance, to prevent spoofing. To enable DMARC, you will add the following TXT record to the DNS server that resolves your Docker mailserver hostname, replacing example.com with your domain name.
_dmarc IN TXT "v=DMARC1; p=none; rua=mailto:dmarc.report@example.com; ruf=mailto:dmarc.report@example.com; sp=none; ri=86400"
