Hi everyone,

I am running CWP on Almalinux8 and recently ran into an email‐delivery problem.

When I checked /etc/opendkim/userkeys/mydomain.com, I discovered that both default.txt (DNS record) and default.private (signing key) are missing.

What I have tried so far:

1. Used the DKIM Manager in CWP to regenerate keys.

2. Rebuilt/restarted the mailserver via CWP’s control panel.

Unfortunately, the key files never appear and the DKIM signature remains invalid.
Can anyone share the exact steps or commands to regenerate the DKIM key pair (default.txt / default.private) for a domain under CWP?

You can use the following command:

opendkim-genkey -b 1024 -d yourdomain.com -D /etc/opendkim/keys/yourdomain.com -s yourselector -v

If that doesn't work, you'll need to resort to a longer checklist, which you can check here:
