Hello, the dkim storage location of the mail server: /www/server/dkim/
It will be automatically established when adding a domain, and the mail server will send dkim information by default, which can be used to prevent mail from being rejected, etc.
If you do not send dkim, please check whether the permissions in the directory are correct
Set 640 to 644, then restart rspamd to send emails to view email source code
chmod 644 /www/server/dkim/xxx.com/default.private
/etc/init.d/rspamd restart
