hello, after the latest kernel update there was also a new linux-image-amd64. Now (I did not restart the node for loading new proxmox kernel yet) apt suggest me the new linux image and at the same time wants to uninstall proxmox completely (see screenshot). The last time I said yes and had to...

thank you very much! does this also remove DKIM signatures?

Hello, what is the option "Hide internal hosts" doing? Regards, Afox

Hello, is the FQDN of the PMG the same as the mydomain entry in Postfix? What domain will the mail come from if for example the PMG has pmg.mydomain.com and the Default Relay is mail.mydomain.com? Regards, Afox

Hello, you write "Proxmox Mail Gateway uses opportunistic TLS encryption". Does this also count for the default relay? So if the default relay has not setup TLS, there won´t be an encrypted transport for incoming mails to this relay? What about mails that come from the default relay to the...

if anyone can give me a hint how to only check internal Mail with amavis I am very grateful!

I don´t know how to do this.

ok, thank you again. I think I have figured out a way to use your product. But there is something I can´t figure out yet. Lets say the existing Mailserver is already running amavis (which is utilising ClamAV, Spamassassin etc.). How can I prevent amavis from checking mails coming from or going...

Hello, does the Spam detector run auto updates or do I have to manually trigger the update process via Configuration->Spam Detector->Status? As I saw the freshclam has its own process so the virus definitions will be updated frequently, I guess. Regards, Afox

I understand. I have one more question: what happens to the "internal" mailtraffic, e.g. if user1@mydomain.com sents a mail to user2@mydomain.com? will this be proxied to the PMG if the relayhost is set. Or will there be no checks at all on this mails? Regards

ok, and is a local IP address fine too or does it have to be the public IP address? My guess is that it doesn´t matter what IP I use, but I want to confirm.

and for the outgoing direction I add in the main.cf of the existing (Postfix-)server: relayhost = #pmgipaddress#:26? What about authentication against PMG to sent mails? Is using an IP-address sufficient in both cases, also a local/internal one? Thanks again!

Hello, thank you! I already read the named chapter. The question I have is if there have to be any modifications to the Mailserver-config, e.g. add the IP of PMG to "mynetworks" etc. As I said I already have a Postfix running and want to put the PMG in front of it, like shown in the named...

Hello, currently I run a Postfix Mailserver. How do I setup this existing Mailserver to work with PMG 5.0? I read the documentation but there is no how-to about implementing PMG into existing infrastructure. Do I understand correctly that the PMG-IP-address becomes the priority 10 MX-record...

Hello, EDIT: my disk is full, although Proxmox tells me I have 89% in use. Problem solved -_- after latest update I get the following when I run the update procedure via Proxmox webinterface: Last time I had a similar error and destroyed my installation by accepting the signature and...

Hello, I did this to get Internet access on my Windows-VMs: https://pve.proxmox.com/wiki/Network_Model#Masquerading_.28NAT.29_with_iptables Everytime I start Windows it asks me what network location it is: home, work or public. How do I stop this? It also seems the network number is rising...

I think I understand the differences between them but I asked what you meant. Also I´d love to see an example of a rule that matches my problem as I don´t get it working with my attempts. I am already stuck at the point of blocking all outgoing traffic as the output policy is set to "accept".

hello, could you please give me an example rule? do you mean the node or the data center layer?

Hello, I want to prevent all VMs connected to a masqueraded vmbr (https://pve.proxmox.com/wiki/Network_Model#Masquerading_.28NAT.29_with_iptables) from internet access with some exceptions like Windows Update and a licensing server needed for Software running on that VMs. Is it possible to...

hello, I tested it over the last days and what I found is that the power consumption increased remarkably. With HT both CPU need 15 Watt more in total.
