bounce mail sending at wrong mailaddress?

Subject: bounce mail sending at wrong mailaddress?
Date: October 3rd 2017

Dear Justin, 


We have a weird issue. On my system there are several lists. 
As normal they use all the same bounce-system. 

Somehow bounce/return-messages are mixed up. One list-admin (VNR) receives mail what should go to another admin (dennisdeals) (and asks me to get rid of this “spam”). 

I cannot find any clue on how this may happen. 

Could surely need some help here. 

Regards, Eef

This mailing list is to discuss the nerdy programming development of Dada Mail -

If you are just looking for support Dada Mail, consult the message boards at:

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.
