Proxmox Mail Gateway 6.1 released!

[martin]

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?

I am not using enterprise version. Can I upgrade it using the pmg-no-subscription repo?

How is before-queue-filtering realized?

 

[timconner]

Huge shout out to implementing DKIM! This was huge for me personally.

 

[Stoiko Ivanov]

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.

 

[Stoiko Ivanov]

Internet Explorer is not supported as browser by PMG anymore - see https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#system_requirements

Try using another browser if possible

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

Thanks
