When saving the recipients in the Post Build Actions > E-mail Notification, the value in the field is not saved.
However it does work if I
1. Fill in the details in both the Post Build Actions > E-mail Notification
2. and enter the same details under Build Settings > E-mail Notification
3. Save job config, the value is then saved
4. I can then go back and configure the job, remove\uncheck Build Settings > E-mail Notification and save, the value is then save in Post Build Actions > E-mail Notification only
But after all that i make a change to the job somewhere else and save the recipients are lost again, and i have to go through the above process again.
