Proxmox Mail Gateway 5.2 available

[martin]

We are very excited to announce the general availability of Proxmox Mail Gateway 5.2!

The Mail Gateway has been updated with all Debian security updates and with a 4.15 kernel. The improved quarantine web interface allows multi-selection of items and you can download emails in .eml format. Version 5.2 comes with a new mobile interface for the quarantine, based on Framework7. We have improved the Message Tracking Center easing the debugging and rule setting. With the new appliance template you can quickly install Proxmox Mail Gateway as a privileged or unprivileged Linux Container. For all improvements and updates please see the release notes for details.

Release notes

• Mobile Quarantine Interface
  * based on the small and modern framework7
  * Deliver/Delete/Whitelist/Blacklist mails in your Quarantine from your mobile device
• Improvements in the LDAP integration
  * allow the use of FQDNs instead of IPs in the WebUI

• PMG-Appliance template
  * Install PMG as a (unprivileged) Linux Container (e.g. in PVE)
  * Introduces the new 'proxmox-mailgateway-container' metapackage, which does not depend on a kernel, and results in a vastly reduced size (and fewer updates)
• Improvements in Logging

• Improvements in the WebUI's TLS configuration
  * pmgproxy can now be configured via '/etc/default/pmgproxy' to disable/enable certain ciphers, compression, cipher selection preference.
• new command: `pmg-system-report`

  * Lets you download the complete source of a quarantined message in .eml format for further analysis

  * Enable users to integrate their own custom check logic by providing a defined interface, which can optionally be enabled, and runs a custom check before the mail gets handed to the virus scanner and rule system.
• Improvements of Blacklist/Whitelist handling in the Quarantine Interface
  * multiselect for removing multiple entries at once
• proxmox-spamassassin
  * Update the shipped rulesets
• PMG-Cluster: full IPv6 support

Do you upgrade from version 5.1 to version 5.2 through the GUI?

Do you upgrade from version 5.1 to version 5.2 through the GUI?

yes. you can update via GUI or via CLI (apt update && apt full-upgrade)

 

[GKrem]

i guess i am a bit of stupid.

i ran all known updates via gui and cli incl. the one mentioned above. My system tells me, that no updates available but in gui there's still Release 5.1-2 and not 5.2-x ?

Is this because i am using the version without subscription? I also downloaded the 5.2 iso but i wonder if i can update a running 5.1 to 5.2 with this?

Hi GKrem

check your repositories.

If you don't know what I mean consult the documentation.

[GKrem]

well - you are right. There was "pve" but not "pmg" in the proxmox line. I did not recognize this on my first check. now i get some more updates. Thx for your assistance.

Thanks for the new release. But it still lacks DKIM signing. When can we expect this to be added? This is mandatory.

As a temporary workaround we were asking ourself if PMGs leaves outgoing DKIM signed mails unchanged when originating from an internal Mailserver that is doing the signing.
Does PMG change the header (e. G. Remove signing) ?

Not for all. Most sign on their mail servers, other are able to configure DKIM via CLI, so no big deal.

no.
