Justin et al,



I’m having a really frustrating problem of certain messages that have an attachments such as an image (jpg, png), pdf, docx content getting stripped out of any messages sent to the list (using bridge).


I trying to ascertain if we have a misconfiguration within DADA or if our mail server (Proofpoint/Exchange 2010).


I’m leaning more towards something in DadaMail because my PHPList server (running on the same machine) doesn’t have this problem it does however use PHPMailer.


Would this be a MTA issue? I’m confused and users are miffed as the list isn’t working.




My Settings in Dada 9.6.1

Default Char set is = UTF-8

Default Plain Text Message Encoding = 7 bit

Default HTML Message Encoding = 7 bit


Messages with an attachment are received with:


This is a multi-part message in MIME format...




And that’s it… a blank message with no other error codes etc.




I’ve attached the sources of two files:


what DADA received (message from the mbox (margaret-message-truncated.txt).

the source of the received message. (margaret-mssg-rcvd.txt) showing that everything south of the attachment is missing (I also had to chop out some of the file to fit under the size restriction of your mail server).


Any thoughts or comments are greatly appreciated.

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.
