Debian opendkim not signing client's outbound messages.
I run a personal email server on a rented Debian Virtual Machine.
Postfix and Opendkim on Debian old-stable and stable. It's a relay "smarthost" for outbound email from workstations on my home LAN. Setup according to the Debian Wiki. I use autossh to forward the VM's submit port onto each workstation. Frequent DMARC reports arrive from Gmail, outlook, and yahoo. Inbound opendkim signature checking is working. #opendkim-testkey -vvvv -d mydomain.us -s myselector# says my keys are ok but not "secure". (That seems to mean DNSSEC is not enabled/working.) The friendly check-auth@verifier.port25.com auto-responder shows outbound messages are not being signed at all. Why is there no log entry? SOLVED Almost InternalHosts line was missing from /etc/opendkim.conf How did I miss that?? I'll update this question when I've tested SASL transmission. Right now my submission port is secured by IP address in Postfix. |
