Howdy Everyone -

Dada Mail v11.3.0 has been released,

Download and Install:


I've written a blog post to help identify the problems this release is trying to solve, as well as where to find the new options that are available:


I know a lot of people have been battling this issue of mysterious unsubscribes, and I'm confident that this release fix more than a few problems.

Changelog (and below):




Google+ Support Dropped

Google+ has been effectively shuttered, so we've removed support for it from the app.


Enhanced One-Click Unsubscription support via Email Headers (per RFC 8058)

Dada Mail has supported "one-click unsubscribe" when a user clicsk one of the unsubscribe buttons/links in the mailing list message, as well as via the List-Unsubscribe email header. The latter of which isn't shown directly to a subscriber, but may be used by their mail reader to provide a mechanism to unsubscribe through it's own UI.

There's a problem though with this List-Unsubscribe header:

Sometimes the unsubscription link in the header is visted by anti-virus software which, after visiting the link will unsubscribe the user without any direct action from the subscriber themselves! This leads to all sort of administration problems, as list owners are losing subscribers who would like very much to stay on their mailing list.

Dada Mail now supports one-click unsubscribe via the List-Unsubscribe header without this problem happening. This is done by following RFC 8058, which provides a mechanism to utilize one-click unsubscribe via the headers, but stops the scenario described above from happening.

Any email reader that supports RFC 8058 will allow your subscribers one-click unsubscribe. Any mail reader that doesn't support this mechanism will still be able to use the fallback, email-only option, also located in the mail header. Either way, incorrect unsubscriptions throught his mechanism shouldn't happen anymore. In our testing, we've found that most email readers actually only support emailing the list owner, when a user clicks the email reader-provided unsubscribe link.

Enhanced List-Unsubscribe header email-only option

If the above mechanism isn't supported by the mail reader, there's a good chance that the fallback is. That fallback being: the mail reader sends an actual email message to the list owner. This email message option has also now been made a bit more useful. In past versions of Dada Mail, an email would be sent to the list owner, telling them the address that wants to be removed as well as the list they should be removed from. It was up to the list owner to go through the list control panel to remove this address.

Starting with v11.3.0, the unsubscription link itself needed to unsubscribe the address from the list will be embedded within the email message the list owner receives, so all they have to do now is click that link.

List-Unsubscribe header can now be enabled/disabled

If one decides instead to not have the List-Unsubscribe header available at all, there is a new option to not enable/disable it from being used. This option is available in the list control panel under,

Mass Mailing: Options: Headers: Use, "List-Unsubscribe" headers



New Options to Complete Unsubscriptions

To coincide with the enhancements to the List-Unsubscribe header, we've expanded the options on what happens when a subscriber clicks the unsubscription buttons/links in mailing list messages themselves.

The three options are now:

One-Click Unsubscription

Once a subscriber clicks on a unsubscription link/button in the mailing list message, they'll be unsubscribed right away, with no further action by the user. Super convenient for the subscriber! And one we suggest, especially since the enhancements to the List-Unsubscribe header have been made and the problem with anti-virus software getting in the way have now been worked out.

One issue with this option though is that a user may inadvertantly click the unsubscription button/link, or forward the mailing list message to someone else, that then clicks that same button/link. Yikes!

Click a link/button in Dada Mail

Once a subscriber clicks on a unsubscription link/button in the mailing list message, they will be presented with a screen, that just asks them to click a link/button to complete the unsubscription. This method may help with people inadvertantly clicking the unsubscribe link/buttons in the mailing list message by mistake. It's the option selected by default. This option is also the newest option added.

Fill in the email address, the submit a form

Once a subscriber clicks on a unsubscription link/button in the mailing list message, they will be present with a screen with a form in it, that just asks them to fill in their email address to complete the unsubscription.

This option is a good one, if you're running a discussion mailing list where email messages are commonly replied to/forwarded to other members.

The unsubscription buttons/links embedded in the message may be clicked upon by a different user than the one that received the message, and this simple form can help stop unsubscriptoions done inadvertantly.

All these options work ndependently to the "one-click unsubscribe" support through the List-Unsubsribe header, which doesn't requires (and cannot have!) any user intervention.

Bounce Handler Enhancements

IMAP Support Added

Set up the Bounce Handler to connect to your Bounce Handler Email address via IMAP. This additional option (along with original option of connecting via POP3) gives you more flexibility on how to connect to your Bounce Handler Email address to help fit more email hosting scenarios. For example, those who are using Microsoft Exchange to administrate email may find better success using IMAP, rather than POP3.

Option to select IMAP is available in the Dada Mail Installer.

IMAP support requires that you separately install the Net::IMAP::Simple CPAN Perl module, or install/upgrade the Bundle::DadaMail CPAN Perl Module.

Instagram Support Added

Add a link to your Instagram profile in your Mailing List Information, the link will be shown in your mailing list messages, along with Facebook, Twitter, Youtube, and your website links

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.
