Proxmox Mail Gateway 6.1 Release Notes
- Based on Debian Buster (10.2)
- Proxmox Mail Gateway is based on the latest stable release of Debian 10.2 (Buster).
- Updated SpamAssassin rules
- Kernel 5.3
- Proxmox Mail Gateway shares the kernel with Proxmox VE and is based on the 5.3 series from Ubuntu 19.10
- DKIM-Signing
- Support for adding DomainKeys Identified Mail (DKIM) Signatures (RFC 6376) to outbound emails
- Configuration via GUI
- Signing happens after processing the email with the rule system, thus ensuring that it leaves the Proxmox Mail Gateway with a valid signature
- Flexible control of which domains should get signed with sensible defaults (the relay domains)
- Inside a cluster, one common selector minimizes the overhead for adding required DNS entries
- Attachment Quarantine
- The
Remove Attachments
action can now optionally deliver the complete email to the Attachment Quarantine - The Attachment Quarantine offers a comfortable GUI for selectively downloading parts of the email for further analysis, or delivering the mail to the original recipient
- Accessible only by the administrators, it offers safety from accidentally open malicious executables, doc-files, and other attachments infected with malware
- The
- Adjustable SpamAssassin Rule Scores via GUI
- Adapt the scores of individual SpamAssassin rules directly in the GUI
- Enables you to adapt the scoring to your environment, thus achieving better ham/spam detection rates
- Mostly for adding a bit of weight to rules, which are good indicators for Spam in your environment
- Selectively disable Rules, which cause false positives for your environment
- Improved handling of Configuration and Rule changes in clustered environments
- The Filtering Engine gets notified about a range of configuration changes which require a reload
- The notification is propagated during the cluster sync
- This reduces the situations where you had to manually restart
pmg-smtp-filter
- Experimental Support for Before Queue filtering
- Proxmox Mail Gateway can now optionally reject an email during the SMTP dialogue, instead of accepting it and silently discarding unwanted email
- This is a requirement in certain situations
- By answering with a permanent failure code (
554
), there is no need to generate a Non-Delivery Report, which could cause your system to get blacklisted, due to Backscatter - Currently incompatible with the Tracking Center, thus needs to be explicitly enabled in
/etc/pmg/pmg.conf
- Improvements to general usability
- Clarification of ambiguously used terms in the GUI and documentation
- More detailed documentation of the Service Configuration Templates
- Downloading of emails larger than 2 MB as eml from the Spam Quarantine now works
- API-Viewer now usable from inside every running PMG installation at https://pmg.local:8006/api-viewer/index.html or just online via https://pmg.proxmox.com/pmg-docs/api-viewer/index.html

Interessiert in verschiedenste IT Themen, schreibe ich in diesem Blog über Software, Hardware, Smart Home, Games und vieles mehr. Ich berichte z.B. über die Installation und Konfiguration von Software als auch von Problemen mit dieser. News sind ebenso spannend, sodass ich auch über Updates, Releases und Neuigkeiten aus der IT berichte. Letztendlich nutze ich Taste-of-IT als eigene Dokumentation und Anlaufstelle bei wiederkehrenden Themen. Ich hoffe ich kann dich ebenso informieren und bei Problemen eine schnelle Lösung anbieten. Wer meinen Aufwand unterstützen möchte, kann gerne eine Tasse oder Pod Kaffe per PayPal spenden – vielen Dank.
