Hello,
Thank you for taking the time to reply.
DKIM does appear to be properly disabled for the domain in question in Mailcow, though :

Thanks in advance.

Hello,

I would like to revisit the topic. Has anyone on the forum managed to get mailcow working with sending via an SMTP relay? (with DKIM OK)

Thank you for your help 🙂

esackbauer

Yes. I did use smtp2go mail relay.
Have you checked the documentation on mailjet how to setup DKIM properly?
Most likely you did something wrong which is not mailcows fault.

esackbauer Hello, thank you for your response. How did you disable DKIM in mailcow? Did you do it as shown in my screenshot in my previous message? Thank you for your help 🙂

esackbauer To disable in Mailcow delete the keys.

DocFraggle "I have successfully deleted the key in Mailcow, but when I send an email from the webmail, it does not use the DKIM key from Mailjet; instead, it uses the old one generated by Mailcow.
Mailjet confirms that my DNS configuration is correct :

nouipoz It’s possible that you have to restart the stack after deleting the key

docker compose down
docker compose up -d

Thank you for your help, but unfortunately, I have already done this. Is it normal for it to appear like this in Mailcow?

nouipoz Is it normal for it to appear like this in Mailcow?

No, this is wrong. It should only show the same names as the configured mail domains.
Either you tried to setup such a mail domain in a wrong way, or your mailcow is broken.

esackbauer It does appear correctly with the configured domain name (I just hid the domain to avoid spam). But is it normal for it to say “missing key” ?

esackbauer

nouipoz is it normal for it to say “missing key” ?

yes.

esackbauer Thank you for your response, In this case, I believe my Mailcow configuration is correct. How can I explain that the DKIM key used when I send an email from the webmail is the one from Mailcow?

esackbauer As mentioned in my previous message, Mailjet confirms that everything is fine. Therefore, I believe the issue is with Mailcow.
