A cryptographic signature appended to every sent email. The recipient verifies it using a public key published in a TXT record.
Why it matters
Proves that the email content was not altered in transit and that it was sent by an authorized sender. A second layer of authenticity alongside SPF.
What's missing without it
Without DKIM, forwarded emails lose their SPF verification and end up in spam. DMARC without DKIM functions only partially.
When it is used
When configuring bulk email sending, changing email providers, or implementing DMARC.
How we use it
selector._domainkey.nazwa-domeny.pl contains the public key; the private key remains with the email sending provider.
