MSH Zimbra Rules Release History

Track our product's evolution and improvements

v1.0.2 - Signature Placement and License Visibility

Released: September 25, 2026

Maintenance release - reply separator settings now reach the milter, license problems are visible from every page, and signatures handle user photos better.

Improvements

  • Signature Position settings now take effect: reply separators edited on the Signature Position page were saved but never used. They are now picked up within about a minute, with no restart. An installation that edited them on an earlier 1.0 version will see those edits applied for the first time after upgrading. 🔗
  • Signatures placed correctly in Outlook replies: a signature now lands above the quoted message in replies sent from Outlook. 🔗
  • License status shown in the navigation: the License entry carries a badge when the key does not validate, expires within two weeks, or covers fewer mailboxes than are synced, with the reason in its tooltip - so a licensing problem is visible from every page. 🔗
  • Messages passed without a license are logged: a message let through untouched because of a licensing problem now appears in Events History with the reason, instead of leaving no trace. Memory used for those messages is also released properly. 🔗
  • Domains page counts corrected: users and groups of a domain nested inside another domain are no longer counted against the parent as well. 🔗
  • Photos found for more users: an account whose photo is stored in the directory as thumbnailPhoto, rather than jpegPhoto, now shows it in signatures. 🔗
  • Cleaner signatures for users without a photo: a signature built in the wizard no longer leaves an empty image behind when the user has no photo. 🔗

v1.0.1 - Mailbox Sync and Licensing Improvements

Released: September 16, 2026

Maintenance release - the Zimbra directory sync imports only real mailboxes and per-mailbox licenses are checked against that count.

Improvements

  • Directory sync imports only real mailboxes: active and locked accounts are synced; closed, maintenance, pending and locked-out accounts are left out. 🔗
  • Internal Zimbra accounts excluded: admin, galsync, spam, ham and virus quarantine accounts no longer appear in the user list.
  • Calendar resources excluded: meeting rooms and equipment no longer appear in the user list.
  • Per-mailbox license check: the License page shows how many mailboxes are synced and how many the key covers; the key is re-checked automatically when the count changes. 🔗
  • Directory Service bind account: the sync now requires Zimbra's own LDAP account instead of the read-only zmpostfix account - update the connection settings after upgrading. 🔗

v1.0.0 - First Release of the New Generation

Released: September 14, 2026

First release of the new MSH Zimbra Rules generation - user signatures, disclaimers, autoresponders and policy rules for Zimbra Collaboration Suite, managed from a web administrator panel.

New features

  • Web administrator panel: browser-based administration running on the Zimbra server - no desktop application to install.
  • Policy rules engine: block, modify, or reroute messages with around 19 actions, including attachment stripping and compression, header manipulation, and forwarding. 🔗
  • Signature rules: personalized user signatures with LDAP variables taken from the Zimbra directory, such as {firstName}, {jobTitle}, and {mail}. 🔗
  • Disclaimer rules: top or bottom disclaimers with duplicate protection, so the text is not stacked repeatedly through reply threads. 🔗
  • Autoresponder rules: automatic replies with loop protection and scheduling. 🔗
  • Message events history: review a log of all processed messages and applied rules. 🔗
  • Rules tester: simulate mail flow and verify rule behaviour without sending real emails. 🔗
  • Multi-domain administration: manage rules and settings for multiple Zimbra domains from one panel. 🔗
  • Access control: restrict administrator panel access with authentication. 🔗
  • Zimbra directory integration: load users, groups, and domains from the Zimbra LDAP directory for use in rules and templates. 🔗
