Running the script with the "stop" parameter kills the process that's
logged in /var/run/opendkim, not all of them.

There might be an ADSP error. Your message to this list wasn't signed, so
I can't tell why that might have happened because I can't see what domain
you're using in your tests. Send a signed message directly to me at this
address and I can tell you what my verifier saw.

Interesting. I don't know what would cause that.

If opendkim-testkey shows that your private and public keys match, then
you would just need to figure out what program is altering your messages
between when you sign it and when the verifier gets it. There are some
steps to do that documented in opendkim/README under "DEBUG FEATURES".
