nouipoz Hello, I have a domain that uses an SMTP relay to send emails, but I can’t disable the DKIM signature on Mailcow. The domain should use the SMTP relay’s signature instead of the one registered in Mailcow. However, I can’t disable it for the domain in question. Is this possible? Thanks in advance.
esackbauer nouipoz I can’t disable it for the domain in question. Sure you can. Delete the DKIM key for that domain in the Mailcow admin GUI general settings (not in the domain config).
ETNyx To be precise you have this flow Mailcow send email to relay server this server is doing final delivery? Than this is not problem on Mailcow part, you are using wrong or badly configured relay, so fix your relay and you will be fine.
