Bounce Handler intelligently handles bounces from Dada Mail mailing list messages.
Messages sent to subscribers of your mailing list that bounce back will be directed to the List Administrator Address. This email account is then checked periodically by Bounce Handler.
Bounce Handler then reads awaiting messages and parses the messages in an attempt to understand why the message has bounced.
The parsed message will then be examined and an action will be taken.
The usual action that is taken is to apply a score to the email address that has bounced the message. Once the Score Threshold is reached, the email address is unsubscribed from the mailing list.
For a guide on using Bounce Handler, see the Dada Mail Manual:

Obtaining a Copy of the Plugin
Bounce Handler is located in the, dada/plugins directory of the main Dada Mail distribution, under the filename, bounce_handler
POP3 Email Account
Bounce Handler works by checking a email address via POP3. (IMAP is not supported).
You will need to create a new email address account manually for Bounce Handler to utilize.
Example: create firstname.lastname@example.org, where, yourdomain.com is the name of the domain Dada Mail is installed on.
Guidelines on this address:
Do NOT use this address for anything except Bounce Handler
No one will be checking this POP3 account via a mail reader.
Doing so won't break Dada Mail, but it will stop Bounce Handler from working correctly, if when checking messages, your mail reader then removes those messages from the POP3 account. If you do need to periodically check this inbox, make sure to have your mail reader set to not automatically remove the messages.
The email address MUST belong to the domain you have Dada Mail installed
Meaning, if your domain is, "yourdomain.com", the bounce email address should be something like, "email@example.com". In other words, do not use a Yahoo! Gmail, or Hotmail account for your bounce address. This will most likely disrupt all regular mail sending in Dada Mail.
Bounce Handler MUST be able to check the POP3 account
Check to make sure that the POP3 server (usually, port 110) is not blocked from requests coming from your hosting account server.
This plugin can be installed during a Dada Mail install/upgrade, using the included installer that comes with Dada Mail. Under Plugins/Extensions (Optional) check the option, Bounce Handler.
Below this option are form fields to put in the POP3 accounts login credentials, as well as a place to test those credentials out.
Once Dada Mail installed, all new mailing lists will use the Bounce Handler's email address as the List Administrator. Any previous mailing lists may need to be manually set to have their List Administrator set to this address - this can be done in the List Control Panel under, Your Mailing List - List Information
Bounce Handler runs in the background on a schedule. Make sure to set Dada Mail's cronjob:
Bounce Email Address
Do you use only one Bounce Email Address for all the mailing lists?
Even though there's only one Bounce Email Address, it is used by all the mailing lists of your Dada Mail, but Bounce Handler will work with every mailing list individually. Each mailing list also has a separate Bounce Scorecard.
