Configuration

The keys folder must contain the following three files.

• keytable
• signingtable
• trustedhosts

The keytable file is a lookup table to match DNS records with the correct selector and key file.

mail._domainkey.example.com example.com:mail:/etc/dkimkeys/example.com/mail.private

The signingtable file contains which email domain matches which DNS record.

*@domain.tld mail._domainkey.example.com

The trustedhosts file contains a list of all host IP addresses which do not need a DKIM signature.

To generate a key for your domain with the selector mail run this command.

opendkim-genkey -s mail -b 2048 -d example.com -D /etc/dkimkeys/
