We are excited to announce the availability of Proxmox Mail Gateway 6.1. The new version comes with some interesting new features.

We have updated the Mail Gateway to Debian 10.2 (Buster) and a 5.3 kernel with ZFS included. The new version 6.1 brings support for DomainKeys Identified Mail signatures (DKIM), a new attachement quarantine, adjustable SpamAssassin scores via GUI, and improved handling of Configuration and Rule changes in a cluster. As an experimental feature, the support for “Before Queue” filtering can be enabled.

I am currently using PMG-6.0-4. Can I setup new PMG-6.1 and directly import and restore the config backup from PMG-6.0-4?

yes, but why not just do the update via GUI with one click?
How is before-queue-filtering realized?

mostly by using postfix smtp_proxy_filter option instead of content_filter - see [0].
The discussion on the mailing-list [1] and the concrete commit [2] should also explain it - as do the docs [3]

I hope this explains it

After a fresh install, I only get a blank page on the web page (https://servername:8006/).
Promox was installed on a DMZ, the only browser i can use is "Internet Explorer 11 Version 11.3383" on a Windows Server 2016.
Note: Last month I try an in-place upgrade from Proxmox 5.2.7 to 6.1and was rollbacked because of the same error - blank page.

After upgrade from 5.x to 6.1, my pmg can't start, the output :

root@pmg:~# systemctl start postfix pmg-smtp-filter pmgpolicy pmgdaemon pmgproxy pmgmirror pmgtunnel
Failed to start pmg-smtp-filter.service: Unit pmg-smtp-filter.service not found.
Failed to start pmgpolicy.service: Unit pmgpolicy.service not found.
Failed to start pmgdaemon.service: Unit pmgdaemon.service not found.
Failed to start pmgproxy.service: Unit pmgproxy.service not found.
Failed to start pmgmirror.service: Unit pmgmirror.service not found.
Failed to start pmgtunnel.service: Unit pmgtunnel.service not found.

I don't understand why this error occurs

Please help me fix it.
check your installed packages with:

> pmgversion -v
I don't know why upgrade finish, pmg disapear.

root@pmg:~# pmgversion -v
-bash: pmgversion: command not found
root@pmg:~# cat /etc/os-release

Hi Tom,

I have known the reason, I do not Update the configured APT repositories ( I use No-Subscription )

So after an upgrade, pmg not work
