We use custom DNS records for our own SMTP servers (see How DNS records work for your Maildoso domains). Because of this custom setup, some third-party tools aren't able to automatically detect our DKIM/DMARC keys — this is expected, and our setup follows Google's guidelines for best deliverability.
To confirm your DKIM/DMARC records, use one of these lookup tools:
DMARC lookup → easydmarc.com/tools/dmarc-lookup
DKIM detector → easydmarc.com/tools/dkim-lookup (select "detect all selectors")
DNS validation → mxtoolbox.com/MXLookup.aspx
Note: because we manage your DNS, you don't add or edit DKIM/DMARC records yourself. If something still looks wrong after checking with these tools, contact support and we'll take a look.
