We moved pmg to a new server. We use PMG to protect 20 domains, most of the domains receive their email on Microsoft 365. Since the move, if one of the 20 domains tries to send email to one of the other domains, the message is resent 8 times then rejected on the 9th attempt. What could I have...

We have a couple users who receive alot of spam and like it that way. Traditionally, I would manually edit /etc/mail/spamassassin/custom.cf, assigning a -10 score to messages addressed to the spam lovers, however I now wonder if there is an official / predefined method of accomplishing this via...

I am planning on configuring a single public IP dedicated server at OVH, every how-to I have read describes using pfSense, I am not against using pfSense, however I like to keep things simple, secure and reliable. So, I can't help but wonder, how will things go, if instead I install nftables...

We are seeing Phishing attacks where the email appears to be from one staff member (employee) to another staff member (accountant), the domain is properly configured with SPF/DKIM records, I was baffled until I looked at the headers. The evil-doer is using authentic (but evil) Return-Path...

I am following https://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE and have run into an issue. How do I convert VMDK to a qcow2 stored on my LVM? Or is there a better solution? df -h reports no useful free space, conversely, I have plenty of free space on the LVM as expressed by...

We have Avast & ClamAV installed on the PME 7.1-2. When looking at "This years' statistics" (/#pmgVirusCharts), I am only seeing messages snared by Avast. Is this normal? My concern is that I have something misconfigured on the ClamAV side, and that it's not catching messages missed by Avast...

Our tracking center is showing no data in database. When I didn't find the data I sought, I tried searching our top 3 recipients as defined on the dash board. Any idea how to solve this mystery? I have used incognito mode, PMG is quite clear, no data: We are using 1/3 of the disk space...

Cofense markets an Outlook plugin and alerting service. When an end-user gets phished, they are trained to click the Cofense icon, I am not sure what happens next, but suspect the message is forwarded to the help desk where the sending email address is blocked. Anyone know if there is an open...
