Thanks again, much appreciated.

There's some very useful information here, thanks for sharing it. May I ask, what do you have your default quarantine/block scores set to? This may impact on custom scores and overrides that others may set as this needs to be balanced with the default scores if outside of the PMG default.

Thanks for your help Onslow. I think it should be possible to change using the templates feature. I'm curious to see if any staff can let us know why this is the default on new installs?

# postconf smtpd_relay_restrictions smtpd_relay_restrictions = ${{$compatibility_level} <level {1} ? {} : {permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination}} # postconf smtpd_recipient_restrictions smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination...

Not that I can see: root@pmg-slave02:/etc/postfix# grep defer_unauth_destination * grep: postfix-files.d: Is a directory grep: sasl: Is a directory These are new installs of v9.0.6 with no customisations to postfix config.

We have a lot of connections coming into our PMG cluster for domains we do not host the email for, eg clients who have since left but left MX records pointing to us. When remote servers try to send to these domains they are rejected because the domain isn't in our "relay domains" or "transport"...

Perfect, thanks for your help Stoiko.

Thanks for your reply. We are already running this after amendments to the files: pmgconfig sync -restart Does "postmap" need running in addition?

Hi all, We will be accepting email for around 80k domains. We are putting together custom scripts to manage the relay domains and transports via the API so that only new/changed/deleted domains generate a call to the API which works fine for us. The issue that we have is that the initial...

Thanks for the reply. I'm speaking to a few partners too but wanted to see if there are any freelancers here so we can consider all options.

Does anyone here offer Proxmox consultancy or management services? We're looking to employ the services of an individual or company on a "one off" basis or recurring contract for some specific tasks on our live Proxmox + Ceph cluster such as: * Managed upgrade to v8 with minimal downtime *...

Thanks for your reply. Our drop in Ceph IOPS is quite a long running issue (we have had a ticket with Proxmox in the past) so I may start a new thread with all versions and metrics we have been gathering to show the issue. My main question was regarding the SSD write cache and whether it was...

Hi, We have a 25 node Proxmox cluster using Ceph as the storage with 200 Samsung PM883 1.92TB SSD drives as OSD's. We are troubleshooting an issue with lower than expected IOPS which isn't a major issue day to day but has caused us problems if Ceph needs to rebalance (eg drive swap). While...

We are struggling with the same issue here... very high IO across the cluster during the rebalance when an OSD is added/removed. We're on Ceph 17.2.5 Do I just run the above 4 commands as root on any of the nodes? Is there a way to see if the new setting has been applied?

We are looking at replacing our ancient incoming email gateway cluster with a PMG cluster. A requirement for us is the ability of our clients to set custom block/accept/quarantine/tag thresholds so we're looking at ways of doing this. It looks like it will be possible by inserting some rules...

We turned off Qemu Agent for all VM's which caused the problem to go away.

We have been looking at Proxmox Backup Server as a good replacement for our current backup system in our Proxmox environment. Unfortunately we have run into the same issue that it seems others are seeing with fs-freeze hanging the VM...

I notice that VM ID's are reused so if a VM is destroyed then a new one created it will use the same ID. This is fine, but it seems that graphs of CPU, RAM, Network, Disk, etc for the new VM will still show usage of the old VM. Is there any way of truncating the usage graphs of the VM ID when...

Thanks Thomas, problem solved :)
