Hi, we receive spoofed phishing emails that appear to be coming from our own domain. In order to filter or quarantine those spoofed emails I activated DKIM signatures for our own emails. Now that all "legitimate" e-mails from our domain are digitally signed via DKIM I was hoping I could filter...

Ok, das war mir bisher nicht klar. Danke! Schöner wäre es natürlich wenn man einzelne Proxy-Funktionen (wie z.B. Greylisting) Whitelisten könnte, aber das ist schonmal ein Anfang.

Ok, danke. Aber damit werden E-Mails für die Ziel-Domain dann von sämtlichen Spam-Checks ausgenommen, oder? Nur das Greylisting abschalten geht nicht?

Aber doch nur für bestimmte Absender, oder greift die Whitelist auch für Empfänger?

Hallo, ist es möglich das global eingeschaltete Greylisting für bestimmte Empfänger und/oder Domains zu deaktivieren? Danke! Viele Grüße, Jörn Bredereck

I didn't want to imply that it's a bug in the software. I'm actually pretty sure it's a faulty rule. But in order to find the fault in the rule it would be helpful to see how the filter parsed and compared the addresses. Unfortunately we don't always have access to our customer's emails...

Obviously. But what if you create an "accept-rule" for xy@domain.com and attachments from xy@domain.com get removed anyway? The logical first step would be analyzing the logs to find out how the filter parsed and compared the FROM-Field of the email with the entries in the white-list. For...

I think you misunderstood me. This thread isn't about my specific filtering problem but about the general logging capabilities of Proxmox Mail Gateway in order to troubleshoot and diagnose ANY kind of filtering problems. I only stated my filtering problem to give you an example WHY verbose...

As for now the biggest problem is the not-working white-listing of certain senders. Today an office attachment got removed even though the sender was whitelisted. How can I troubleshoot problems like these? Is the any way to increase the verbosity of the logs?

Hi, I'm using 5.2.1 and would like to know how to troubleshoot/debug the mail filter. The information provided in /var/log/mail.log is very limited. For example I'm having issues with the office-attachment filter. In some cases it's filtering attachments even though there should be a matching...

Hi, thanks to everyone who answered. I will check out pve-zsync. That sounds promising. And in the meanwhile I figured out how to migrate VMs to LXC. But since we're using ZFS in most of our VMs LXC is not really an option. Or is there any way to run a zpool inside an LXC container?

I'm in the process of evaluating Promox with LXC as a replacement for our Citrix Xen environment. As much as I like the openness of Promox I'm little bit frustrated with the use of LXC. But maybe that's just due to my lack of experience. So I would love to hear from the LXC power users in this...

Is there NAT involved? If so then it's more likely that you are missing the necessary PPTP/GRE-NATing modules. modprobe ip_nat_pptp modprobe ip_conntrack_pptp modprobe ip_gre

Wow, that's easy. Ok, got it. Thanks a lot! Yes, that's right. But in most cases I'm just adding or removing bridgs. We run separate internal networks for the VMs to seperate them on layer2.

Hi, I'm currently evaluating Proxmox VE and so far I love it. But there's one thing that could be an absolute "show stopper" for our usecase: Whenever I make a modification to the network setup (e.g. add a new OVS bridge) I need to reboot the entire host along with all the VMs on it. This is an...
