Hi there, I've noticed some emails with infected attachments stuck in the spam quarantine but with no virus alert being triggered although it seems that the virus is detected by Avast (when I test it as outgoing mail it gets triggered properly). Just wondering if there is any order in spam...

Just wanted to ask all of you out there, I have very bad experience with ClamAV, quite all viruses passes AV test on PMG. Like literally it is magic when some virus is catched by ClamAV. These days we receive a lot of Word/macro enabled virus downloaders/droppers that never get caught by...

Hi folks, I've experienced ransomware attack that originated from email attachment. The fact that the infected file passed through all checks (ClamAV on PMG, even local AV) forces me to think about tightening the rules a bit more here. We are using Windows clients only (for end users) and I...

Hi there, I want to run Proxmox on HP DL160 Gen9 and use ZFS. There is HP P440ar in the server, now in RAID mode, but I've read it is possible to switch this controller to HBA. I have similiar setups already running, but I use HW RAIDs (RAID6 or RAID1/10) and LVM on top of it. What is unclear...

I do have sender now that is being blocked by RBL even though I have whitelisted it in "Configuration -> Mail Proxy -> Whitelist". As I've read the docs for this option: All SMTP checks are disabled for those entries (e. g. Greylisting, SPF, RBL, …). But still I am not able to make exception...

I have configured maximum spam size option to be 262144 bytes (256kB) (default value in fact) but I still get larger e-mails scanned and they eventually end up in quarantine (or maybe blocked?). I really don't understand this behaviour. Can anybody explain me if I understand this option wrong? I...

Today there was ready a really bad surprise for me, as on PVE host with LVM-thin I started to receive notifications about disk I/O write problems and then all of VMs (Windows) slowly hung up... Just after the server reboot and when first VM started to boot up I've received such error: space map...

Hi, I'm just fine tuning PMG spam filtering, and wanted to ask if there is possibilty to whitelist outgoing email addresses (adjust their SA score with some negative value). It would help to prevent false positives on emails, that were seen on outgoing communication and are (in theory) safe...

Hello there, please can anybody explain me DNSBL Threshold config value in Mail Proxy/Options? Does it mean that at least X DNSBL hits must be triggered simultaneously to get message rejected? I would appreciate better description for some config values in documentation, this one is not even...

Hello all, I wanted to ask here for your experiences running PVE with local storage using ZFS on HP gen9 or gen10 servers. In near future i am planning to deploy two PVE installs on such two servers. I plan to use RAID1 (mirror) for boot drives and RAID6 (RAIDZ2) for data drives. I'm familiar...

Hello all, I think this is neverending question, but sometimes I'm facing swapping issue that I really do not undesrtand. I have two hosts in cluster (not HA), both running 96G of RAM. I keep enough of free RAM on each to be able to migrate all of VMs to one or other if needed, so total...

Hello, the procedure of removing node from a cluster is clear for me, but I wanted to ask if it is safe to reinstall removed node and assign it the same name and the same IP that it previously had? I have some standalone PVE node that I want to move VMs to other nodes at existing cluster, so I...

Hello everyone, I've created and set up my first unprivileged LXC container, everything was okay until I've run into problems with backing up this LXC. The backup is failing with this error: ERROR: Backup of VM 320 failed - command 'set -o pipefail && lxc-usernsexec -m u:0:100000:65536 -m...

Hello, I'm wondering why when vzdump starts (once overy week), that it suddenly empties ZFS ARC cache. If you take a look at the graphs you see increase in CPU utilization (vzdump starts using pigz) and on the same time there is steady memory usage drop, which corresponds to lowering ARC memory...

When I am handling quarantine emails in a bulk it is quite irritating that I need to use mouse to trigger delete or deliver actions. It is already possible and very convinient to mark multiple emails using shift+arrows and I am using it a lot. Sometimes I even hit the wrong action (deliver...

Hello all, I'd like to get someone's view on using min/max memory values, ballooning device and KSM sharing, all those things related to memory management (KVM and Windows Server guests especially). I do understand how they works and what they do, at least i think so :eek:)... But my point is...

Hello, nothing critical, but just wanted to know why there is this limit preventing me to remove more than cca 30+ spams at once from quarantie. Always need to split the cleanup to multiple rounds... Error given: Parameter verification failed (400), id value may only be 600 characters long.

Hello all, I'm not able to block emails from unwanted sources, so I just want to clarify that I am doing everything right. I do have "Who object" with name "Newsletters" and I've filled it with emails and whole domains that I want to block. I've created Mail Filter action with name "Block...
