OpenDKIM on a Mac
DKIM signing & verification milter (self-hosted) · Mail
OpenDKIM signs outbound mail and verifies inbound DKIM signatures as a Postfix/Sendmail milter (default :8891). Generate a key, publish the TXT record (the Cloudflare pane can help), and point your MTA at it so your mail authenticates and reaches inboxes.
