Regarding this docs
http://confluence.public.thoughtworks.org/display/CCNET/Email+Publisher

there is 'Exception' notification. That works well (except for
modifiers, but thats not documented either).

But it can't be currenly possible to send all exception states to 1.
group _only_ and failed builds to 1. and 2. group oth. Like this:

                   <group name="buildmaster">
                          <notifications>
                               <notificationType>Always</notificationType>
                          </notifications>
                   </group>
                   <group name="developers">
                          <notifications>
                               <notificationType>Failed</notificationType>
                               <notificationType>Success</notificationType>
                          </notifications>
                   </group>

I think its quite common request to _not_ send exception to developers
(since they can't handle it anyway).


Failed are now considered as 'Failure'+'Exception', which is not
documented well.

Excerpt from EmailMessage.cs:
               AddRecipients(recipients,
EmailGroup.NotificationType.Always);
               if (BuildStateChanged())
                   AddRecipients(recipients,
EmailGroup.NotificationType.Change);
               if ((result.Status == IntegrationStatus.Failure) ||
(result.Status == IntegrationStatus.Exception))
                   AddRecipients(recipients,
EmailGroup.NotificationType.Failed);
               if (result.Status == IntegrationStatus.Success)
                   AddRecipients(recipients,
EmailGroup.NotificationType.Success);
               if (result.Fixed)
                   AddRecipients(recipients,
EmailGroup.NotificationType.Fixed);
               if (result.Status == IntegrationStatus.Exception)
                   AddRecipients(recipients,
EmailGroup.NotificationType.Exception);

Changed by request on http://jira.public.thoughtworks.org/browse/CCNET-1046
I dont think thats good change, but ok. We can add another
notification for 'Failure' only, perhaps?
