1. Summary

The Mail Stronghold Zimlet (MSZ) is a Zimbra Collaboration Server (ZCS) plug-in developed and commercially licensed by Mail Stronghold ©2011, all rights reserved.

  • Current version: 1.0
  • Release status: General
  • Release date: October 1, 2011
  • Customer feedback: Contact Us

2. Requirements

These are the requirements and assumptions made by the following instructions on using MSZ.

  1. Zimbra server: Obtain the latest version of MSZ from the Mail Stronghold provisioning and installation team who will contact you after you complete your order. You must install MSZ on your Zimbra server, or have had it installed for you (we will do it free-of-charge by request). MSZ must be activated and enabled for your mailboxes (by Server, COS, domain or individual Mailbox). See administrator Install instructions.
  2. End-use Licensing (MSZ): you or your organization must be a Mail Stronghold customer with an active Commercial Plan in good standing. Please Contact Us to upgrade from a Community Plan, or activate service.
  3. Multi-tenant Licensing (MLA): For those customers in a “shared” hosting environment, your hosting company (Host) must authorize the Mail Stronghold Multi-tenant Licensing Agreement (MLA), essentially indicating that your Host will only activate MSZ for Mail Stronghold Commercial Plan customers. Note that the MLA is free-of-charge, and while there may be other benefits for your Host, the MLA is only required for “Shared” hosting, not for dedicated servers, or customers managing their own, on-premises Zimbra servers. Please Contact Us with any questions about the MLA.

3. Definitions

Various words and terms with specific meanings are used in these instructions.

  • Admin or Administrator: One of your team members responsible for at least basic Zimbra Server systems maintenance, at a minimum, adding, changing and deleting Mailboxes. Commonly a person responsible for IT at your organization, with Privileged access to your Zimbra Server for control and maintenance. Your Admin(s) is/are your only authorized point(s) of contact (POC) for support from Mail Stronghold.
  • Blacklist: A list of Senders blocked from sending you email. Senders on your Blacklist who send you email will be blocked by Mail Stronghold, and you will not receive email from them again unless you unblock them by removing them from your Blacklist. Blacklists may be Personal, that is: only impacting one User’s Mailbox, or Privileged and domain-wide, that is: impacting all Users across one particular domain name (ie: yourdomain.com). Unlike Spam identification, Blacklists do not use email content scanning to identify messages to block, nor may they apply service-wide. Blacklists only block Senders.
  • Header: The first part of an email, not only containing the Sender and Recipient, but also other information used by your Zimbra server and Mail Stronghold to, for instance, identify uniquely the email message. The Message Header in its entirety (including all available Header Fields) is commonly referred to as the Full Header. Right [control] click on an email and choose Original Message to view the Full Header.
  • Junk: the mail folder/directory where Spam is placed automatically after you identify any given email as Spam, or email is identified as Spam by Mail Stronghold.
  • Mailbox: Typically means a User’s Inbox, may mean all of any one particular User’s email, including all the folders containing it.
  • MSZ: Mail Stronghold Zimlet.
  • Privileged: Access and/or rights reserved for your Admin(s).
  • Quarantine: By default, Spam is “quarantined” in Users’ Junk folders. Messages carrying viruses identified by Mail Stronghold are quarantined outside of Users’ mailboxes, not delivered to Users. Optional email alerts about quarantined items may be requested by your Admin. Also, your Admin may request Mail Stronghold to be configured to also quarantine Spam without delivering it to Users’ Junk folder, as well as send emails alerting Users of quarantined messages.
  • Recipient: The User or system receiving a particular email message. When someone sends email to you, you are the Recipient.
  • Sender: The User or system sending a particular email message. When someone sends email to you, that someone is the Sender.
  • Server: is your Zimbra Collaboration Server (ZCS).
  • Spam: is unsolicited and bulk email. Marking an email as Spam trains Mail Stronghold to identify the content of the message as more probably Spam, increasing the likelihood of Mail Stronghold’s automatically placing future messages with similar content into your Junk folder. In this way, all Mail Stronghold users contribute to the effectiveness of Mail Stronghold’s Spam-recognition.
  • User: is typically you! Used to talk about the individuals using Mail Stronghold, as differentiated from Privileged Users like Admins.
  • Whitelist: A list of Senders who will never be marked as Spam by Mail Stronghold. That is: email from Whitelisted Senders should always be allowed through Mail Stronghold. Whitelists may be Personal, that is: only impacting one User’s Mailbox, or Privileged and domain-wide, that is: impacting all Users across one particular domain name (ie: yourdomain.com).
  • Zimbra or ZCS: Email and collaboration server software made by the company Zimbra, part of the VMware company.
  • Zimlet: A plug-in for Zimbra that enables some sort of extra functionality, such as integration with a cloud security service so that Users may independently manage Whitelisting and Blacklisting without leaving their usual web client.
