I cannot deliver mail from one KumoMTA to another one using a certificate signed by my own CA. The error message I see is failed: invalid peer certificate: UnknownIssuer from the client MTA. I’m using ghcr.io/kumocorp/kumomta:2024.06.10-84e84b89-arm64 and I already added the CA to the list of trusted certificates of that container (cp ca-root.crt /usr/local/share/ca-certificates/ && update-ca-certificates).
I believe the issue I’m seeing might be related to https://users.rust-lang.org/t/rustls-unknownissuer-with-own-ca/88575/4
Does anybody know what I should do to fix this?
