I have configured dkim, spf and dmarc dns entries, and a receiving mailserver’s rspamd states that dkim verification succeeded (R_DKIM_ALLOW Symbol green with -0.2 score), so everything seems setup correctly. But in nethserver cockpit I see:
What could here be the problem? I copied the dkim entry and created a corresponding TXT record at my provider. The host entry is default._domainkey.ourdomain.com and the rest was pasted from dkim configuration on my nethserver. The .ourdomain.com suffix is created automatically upon saving the new TXT record even if I only want to have default._domainkey, as proposed within nethserver after saving it becomes default._domainkey.ourdomain.com. I asked my provider if it is possible to have it saved without this and they say no.
