DKIM (DomainKeys Identified Mail) is an email authentication method using digital signatures. Protects against email spoofing.
Generate keys with our tool, add a TXT record to your domain DNS. Detailed instructions on the page.
We recommend 2048 bits — optimal balance of security and compatibility. 1024 is outdated, 4096 may not fit in a TXT record.
