Very useful, but unmaintained, dkim email message signing program.
All the time I’ve been using it the sysvinit script to start it has been a mess and various workarounds are needed. With the refusal to accept a different location for private.key being particularly annoying.
At least on debian and ubuntu thisis the case.
Even though you are supposed to be able to override default settings in
/etc/dkimproxy/dkimproxy_out.conf it does not happen.
This is only for dkimproxy.out because that’s all I use but should be adaptable to dkimproxy.in
Mask the sysvinit script. (even though there’s currently no service file for dkimproxy the below still works).
systemctl mask --now dkimproxy.service

Create (or edit) /etc/dkimproxy/dkimproxy_out.conf with options of your choosing which will now be honoured.
