Deactivation of Status Notification Emails in NoSpamProxy

When using the NoSpamProxy queue based mode, the gateway solution acts as a message transfer agent (MTA). This results in sending status messages to the original sender of a message. Status messages include delayed status notifications or non delivery reports. Especially when using a SMTP based archive connector you want to not send status messages.
Deactivation of status messages is configured in the Gateway Role configuration file.
Configuration file location:
C:\ProgramData\Net at Work Mail Gateway\Configuration\Gateway Role.config
Create a backup of the configuration file first. If the gateway role cannot be started after modification just restore the backed up configuration file.
Add the the following configuration to the Xml node netatwork.nospamproxy.proxyconfiguration.
<queueConfiguration sendDelayNotificationOnlyWhenRequested="true" />
The node should look like this:

<netatwork.nospamproxy.proxyconfiguration hostDomain="YOURDOMAIN">
  <queueConfiguration sendDelayNotificationOnlyWhenRequested="true" /> 

Save the file and restart the gateway role.
The configuration must be done on each gateway role. The configuration change is persisted when applying a software update.
