We have a multi-module job. Mail-Notifiers in module POMs are defined as follows:

<ciManagement>
<system>hudson</system>
<url>https://server/hudson/</url>
<notifiers>
<notifier>
<type>mail</type>
<sendOnError>true</sendOnError>
<sendOnFailure>true</sendOnFailure>
<sendOnSuccess>false</sendOnSuccess>
<sendOnWarning>false</sendOnWarning>
<configuration>
<recipients>a.b@c.de</recipients>
</configuration>
</notifier>
</notifiers>
</ciManagement>

These do not work properly. As far as I understood the system the email-entries in module configurations are modified automatically (see attachements). This seems to work initially. But when notifiers-entries in module-POMs are defined later on they will be ignored. Therefore no email-notifications are sent and our developers cannot fix the problem...
