Non interpersonal message

Problem:

Rules are not executed upon "Non interpersonal" messages, consequently the signatures are not added. The log files contain the following message:

Non interpersonal message. Skipping it.

Solution:

Sometimes CodeTwo Exchange Rules 2007/2010/2013/PRO does not follow the rules despite the fact that they are defined properly, for example a signature is not added. This problem affects non-standard, not user-made messages. Those may be invitation emails sent from a calendar, system messages or actually real emails but already processed by a third party software. They are not processed by Exchange Rules because usually their structure and formatting differ significantly from regular emails. The software is purposely set not to process such messages. Be aware, the software cannot identify which message is actually interpersonal and which is not. This is judged by appropriate email header entries. Some actually interpersonal emails can be marked in headers as non interpersonal - there is nothing that can be done software-side to verify that.

There is a way, however, to force Exchange Rules to process all messages, including non interpersonal ones.

  1. If you are using CodeTwo Exchange Rules 2007(version prior to 4.x)/2010(version prior to 3.x)/2013(version prior to 2.x)/PRO 1.x you can do it by adding a Windows Registry entry:
    1. Hit Windows + R, type regedit and press Enter to open the Registry Editor.
    2. In the registry editor search for or create a path:
      HKEY_LOCAL_MACHINE\Software\CodeTwo\CodeTwo Exchange Rules <ver.no.>\
      where <ver.no.> is the version number of the software.
    3. Click the right mouse button to add a value of a type DWORD named ProcessNonIPM. Click twice on a newly added record and set the value to 1.
    4. Restart MSExchangeTransport service.
  2. If you are using CodeTwo Exchange Rules 2007(version 4.x)/2010(version 3.x)/2013(version2.x)/PRO 2.x you can do it by modifying config file:
    1. Go to installation path. Default installation path is:
      %programdata%\CodeTwo Exchange Rules\Config
    2. Open Agent.xml file.
    3. Find the follow section:
      <ProcessNonIPM>false</ProcessNonIPM>
    4. Change "False" to "True".
      <ProcessNonIPM>true</ProcessNonIPM>
    5. Save the file
    6. Restart MSExchangeTransport service.

From now on, Exchange Rules series programs will process messages from the category "Non interpersonal".

Despite setting this attribute CodeTwo Exchange Rules family will not process non-delivery reports (NDR).
