    Issue with caching when destination is offline

    Hi @Stoiko Ivanov Still have to find the reason, why `RCPT from unknown[10.10.10.1]:` is being gererated, but there I suspect a misconfiguration on our NAT. The reason for the `Recipient address rejected: Domain not found` lies, as you suspected, in DNS. We use a DNS-Resolver on our second...

    [SOLVED] lets-encrypt-connection-refused-status-400: acme via dns-plugin

    I'm having an issue with the same error message as reported here , but we're using the DNS-validation plugin. This week we also had an issue with acme.sh, but this is fixed in the development branch, see the Issue on gitlab. Does anyone have an idea where this might fail? Jun 15 05:18:08...

    [SOLVED] PMG ACME-DNS with CYON: failing to issue certificate

    Hey Community, I'm currently setting up our first PMG and I'm stuck with the certificate-ordering via ACME. I used the CT-Template: proxmox-mailgateway-container: 6.4-1 (API: 6.4-4/1c8a73c7, running kernel: 5.4.114-1-pve) with the following plugin-settings DNS-API: cyon API-Data: export...
