dkim not working about wildduck-dockerized

[MinisculeGirraffe]

Can confirm. DKIM key is added with the proper selector and the containerized setup doesn't sign DKIM headers. Specific to the dockerized version. DKIM keys have been added via the API.

Will edit later with logs.

Any idea why it doesnt work for image:nodemailer/zonemta-wildduck ?
I have installed on bare server https://github.com/nodemailer/wildduck/tree/master/setup and dkim works well, I have created docker image on rancher and passed config from working bare setup version.

Is it possible to get help from you using $$$?

I'll have to test and check. There's shouldn't be any difference between the normal install and the install in the docker container. I'd have to find some free time in a weekend to check.

I assume you mean me :)? I'm available for a little freelance work in the weekends. I'd charge about €120 an hour. You can contact me for that on [email protected] if you desire.

It would be great!

The main reason is that there is no configured dkim plugin in zone-mta. I think it will be better to put this procedure inside setup.sh. For now you can do as follows: replace all files from ./config/zone-mta/ to ./config/zone-mta/config folder and create following ./config/zone-mta/config/plugins/dkim.toml file:

["dkim"]
enabled = true 

Find an example of the plugin here, copy it inside ./config/zone-mta/plugins/dkim.js, generate openssl certificates and place them inside ./config/zone-mta/keys (here you can find generation procedure of certs, DKIM_DNS and DKIM_SELECTOR ). Replace DKIM_DOMAIN_NAME, DKIM_SELECTOR and DKIM_KEY in ./config/zone-mta/plugins/dkim.js. Don't forget to add next TXT record for DNS verification DKIM_SELECTOR._domainkey.MAILDOMAIN with DKIM_DNS value and mount volumes in docker zonemta:

    volumes:
      - ./config/zone-mta/config:/app/config
      - ./config/zone-mta/keys:/app/keys
      - ./config/zone-mta/plugins:/app/plugins

@AaronPorts Het wildduck zonemta plugin does the dkim signing with keys from the database. There is no need for a separate dkim plugin.

I still haven't been able to find the time to look into this, sorry

[AaronPorts]

@louis-lau Do you mean using http://localhost:8080/dkim api call? I tried it but no luck.

[louis-lau]

Yep, if you add keys there with the right selector the wildduck zonemta plugin should take care of it.

[louis-lau]

It looks like I made a mistake in the default zone-mta configuration. A lot of thanks to @taxilian for figuring this out.

This should fix it: b1ba2c6

Either run the setup from scratch, or make the same change to your current config, and let me know if dkim now works for you!
