v11.15.0 Released!

From: "Justin John justin@PROTECTED [Dada Mail Developers]" <dadadev@PROTECTED>
Subject: v11.15.0 Released!
Date: August 31st 2021

Hello everyone,

v11.15.0 has been released!

Download and install:


This version has protection from link prefetching, which can cause havoc on a mailing list’s functions. I’m not even kidding. Here’s a blog post showing an example of how this can happen in something as widely used as Apple’s Mail app:


I’m suggesting this is one of those, “need to have” upgrades. If you’ve been putting off upgrading your Dada Mail, now’s a really really good time.

Changelog (and below):



This is a release that includes some features as well as some fairly important security enhancements. Please read the whole changelog for this release to understand the important changes made.


jQuery upgraded from v2.2.4 to v3.6.0

Older versions of jQuery have known potential security issues that have been fixed in newer versions. No known security exploits in Dada Mail have been found from this older version of jQuery, but we suggest upgrading your version of Dada Mail to stay as safe as possible.

Link Prefetching Protection

Links in email messages in Dada Mail that cause an action, like "subscribe", "approve message", "reject message", etc can be automatically triggered without the user's knowledge by email readers that prefetch the content from the link. Link prefetching happens for a few reasons, including filtering links for malicious content or generate previews.

Starting in v11.15.0, Dada Mail has safeguards against link prefetching that leads to an action, by translating these "GET" requests to, "POST" requests. These include:

  • Subscription Confirmations

  • Unsubscriptions

  • List Owner Accept/Rejecting Subscriptions

  • List Password Reset

  • Clickthrough Link Tracking

  • Profile Activation

  • Profile Password Reset

  • Moderating Discussion Messages

This is a farly large issue, and we do suggest everyone to upgrade to v11.15.0 (or later).

All subscribers of this list may post to the list itself.

Some on topic... topics include:

  • Positive Crits on the program (I like, "x", but, "y" needs some work - here's an idea on how to make this better...)
  • Bug/Error reports
  • Bug fixes
  • Request For Comments on any changes to the program
  • Help customizing Dada Mail for your own internal needs
  • Patches
  • Language Translations
  • Support Documentation/Doc editing, FAQ's, etc.
  • Discussion of any changes that you would like to be committed to the next version of Dada Mail -

At the moment, there aren't many people with CVS access for Dada Mail - if you would like CVS access, please first talk about the changes you propose and how it will affect the program. If the idea is sound and agreed upon, the change will be comitted. A good track record of this will allow you to have CVS access. Some reasons that patches will not be accepted is if the patch breaks compatibility with a previous version of the program, the patch is too centric to your own problem or the patch simply isn't very good.

Please, please please familiarize yourself with the documentation at:


Since no one wants to answer the same question twice.

Another sneaky reason for this mailing list is to test out the discussion list capabilities of Dada Mail, since Dada Mail is used for the mailing list itself.

NOTE - because of this, there may be times that this list will be somewhat broken. Although we're not planning on breaking the program by using it, we're giving you the heads up that this may well happen anyways.
