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
