Zimbra Zimlets : The Ultimate Guide to Customizing Business Email
What is a Zimbra Zimlet?
A Zimbra Zimlet is a small software add-on or extension. It allows your Zimbra Webmail system to connect and talk to third-party software applications. Think of a Zimlet like a plugin for your smartphone. By adding a Zimlet, you can unlock new tools, automate tasks, and complete extra work without ever leaving your main email screen.
For many businesses, shifting between different browser tabs to check a map, track a package, or schedule a calendar invite wastes valuable time. Zimlets solve this problem. They create a “mash-up” of your favorite work tools directly inside your email user interface.
By default Zimbra Zimlets is available out of the box deployment and pre-defined, such as:
- Dropbox
- Slack
- Nextcloud
- Zoom
- Jitsi
How Zimlets Enhance Your Daily Business Productivity
Zimlets are built to make your business communication faster and easier. Instead of cutting and pasting data from an email into an external browser window, Zimlets read important text in real-time. This allows users to complete tasks instantly using two main tracking methods:
1. Hover Previews (Mouse-Over Actions)
When you move your mouse cursor over specific words in an email message, a Zimlet can show you real-time data previews inside a small pop-up bubble:
- Physical Addresses: Hover over an address to see a local map or get accurate driving directions.
- Dates and Times: Hover over a specific time to view your personal calendar availability for that day.
- Names & Contacts: Hover over an email address to see saved phone numbers and details inside your corporate address book.
- Business Metrics: Hover over a tracking number, part serial number, or stock equity to check inventory and shipment status immediately.
2. Right-Click Quick Actions
Right-clicking a piece of information allows you to launch instant workflows. You do not need to open a separate application:
- Phone Numbers: Right-click a number to make an instant voice call using a softphone or VoIP application.
- Meeting Requests: Right-click a date mentioned in an email text to instantly schedule a formal corporate meeting.
- Data Security: Right-click an unknown sender to verify security tokens or update internal contact records safely.
Key Examples of Enterprise Zimlets
The Zimbra framework supports a massive ecosystem of external software integrations. Some of the most common productivity tools used by corporations include:
- Video Conferencing Plugins: Integrations with systems like Zoom or BigBlueButton let you inject calendar meeting links directly into invites with a single click.
- Cloud Storage Connections: Sync your email attachments directly with secure cloud drives like Dropbox or Zimbra Drive to save local server storage.
- Data Loss Prevention (DLP): Advanced security Zimlets actively check out-bound emails. They warn employees if they are accidentally sending out sensitive corporate data like credit card or registration numbers.
- Custom Headers: Specialized system administration tools can inject specific email security tags to ensure compliance with strict local privacy frameworks.
How to Deploy and Manage Zimlets on Your Server
Zimlets are packaged as lightweight .zip files containing all necessary backend scripts and code assets. A system administrator must handle deployment using the Zimbra Command Line Interface (CLI).
The Core Deployment Commands:
To install a new Zimlet file across your network, an IT administrator logs into the mail server as the zimbra user and executes the following core command sequence:
Deploying the Asset:
zmzimletctl deployRestarting Mailbox Services:
zmmailboxdctl restart
Running this automation creates an entry in your LDAP directory server and copies the file system scripts to each node. Administrators can also grant or deny access to specific groups of users based on their Class of Service (COS) profiles using Access Control Lists (ACLs).
