Hi, We use postfwd2, which ratelimits stuff based on the amount of RCPTs. I noticed that postfwd2 counts messages twice, because each one has RCPTs: the original message, and the one relayed to pmg-smtp-filter and then re-injected (using `content_filter`). Here's someone else with a similar...

Hi, This question is only slightly PMG-related. I am mostly looking for other users' input. I use PMG as a smarthost for several purposes, where email sent from a specific domain is sent by a specific system user. Using the mail tracking functionality, I can look up which email was sent from a...

Hi, From the admin guide and forums, I gather that email sent to the internal port should not be SPF-filtered. It makes no sense to do so for relayed mail, where PMG is a smarthost. However, this mail is being filtered: it's rejected because of the KAM_DMARC_REJECT SpamAssassin rule (6 points...

https://pve.proxmox.com/pve-docs/chapter-qm.html says: The `qmshutdown` task is ended after 'Shutdown timeout' (as the VM did not respond to the ACPI signal). However, unlike the documentation says, the VM is not force stopped. It still has the state `running`. The task log is attached...

On a 12-node cluster, due to a backup issue, several CT's RBD images became read-only. Issue: backups caused RBD images to become read-only On all nodes, a backup job ran at the time of the issue. The backup jobs on two nodes (`g04s01` and `g04s07`) failed. On `g04s07`, the following was...

I would like to supply custom user data for Cloud-init using `--cicustom`. I would like to re-use a single snippet for all VMs. However, the default user data contains the `hostname` key. Is it possible for Proxmox to substitute it dynamically?

Does a Cloud-init image exist for Proxmox Mail Gateway?

How do I stop PMG from removing the custom `source` line -which is supported according to the documentation- in `/etc/network/interfaces`? Context: I have some custom interfaces that PMG should not manage. `/etc/network/interfaces` says: The documentation at...

VM configs (`/nodes/{node}/qemu/{vmid}/config`) contain configuration strings, such as: local-zfs:vm-100-disk-1,aio=native,cache=unsafe,discard=on,iops_rd=20,iops_rd_max=30,iops_wr=20,iops_wr_max=30,iothread=1,mbps_rd=5,mbps_rd_max=10,mbps_wr=5,mbps_wr_max=10,replicate=0,ro=1,size=20G,ssd=1...

When creating a backup of a VM not previously backed up to PBS, 'backup was done incrementally' is almost always shown: INFO: backup is sparse: 2.83 GiB (1%) total zero data INFO: backup was done incrementally, reused 4.91 GiB (2%) I take it 'incremental' means space was 'reused' as the backup...

It has caught my attention that rewritten addresses with SRS are not signed with DKIM, because PMG looks at the domain after @ instead of the rewritten domain: not DKIM signing mail from SRS0=duAC=HO=cyberfusion.nl=wedwards@prorelay.nl So in this case, email from cyberfusion.nl is signed with...

Is it possible to use decimals for 'Spam Filter' rules? I have a *lot* of spam emails that have a spam level of 1.9 ...

What is the correct way to add DKIM domains from CLI? Or can we simply write to `/etc/pmg/master/dkim/domains` and run `pmgconfig sync`?

I just published a (very basic) Python program called `virtualisation-resource-distributor` on PyPI. It'll try to run resources in a Proxmox pool on as many different nodes in as many different failure domains as possible. Our use case is spreading VMs providing the same service redundantly over...

How should a DKIM selector be removed? (Doesn't seem to be documented :) )

I'm seeing this on my cluster nodes: Nov 2 17:35:14 mgw0-1 sshd[14200]: Received request to connect to path /var/run/postgresql/.s.PGSQL.5432, but the request was denied. I copied the default `/etc/ssh/sshd_config` from a default Proxmox Mail Gateway ISO install, but I'm still seeing this...

Assuming an existing Proxmox cluster with node1, node2, node3 and node4: node1, node2 and node3 are used as Ceph monitors, managers, MDSes and OSD nodes. node4 is already in the Proxmox cluster, but is only used as a 'compute' node; pveceph is not installed. So: node1 to node4 are in the...

When using PMG as an SMTP relay, I want the SPF check to be skipped for mail offered to the internal SMTP port; only the PMG servers are specified in SPF records, not the internal host using the PMG smarthost. I can of course add custom SpamAssassin rules for this, but before I do that, I'd...

I have the following setup: Traffic from VMs is routed through router VM Traffic to VMs is routed through router VM Two days ago, I started seeing packet loss on IPv6 traffic from VMs to the router VM and the other way around. This started after rebooting the router VM. It seems like...
