[TYPO3-caretaker] Caretaker sends no emails

[Nina]

Hello Martin,

the problem is allready that I cant get one node to send a mail.
I went in the BE-Overview, select an Instance and choose 
Actions->refresh forced. I wait till the window refreshes... and 
nothing happens.
In the BE is shown an error. But why dont he send a mail? What could i 
have forgotten?
The "Instance Group" has an contact witch has an adress and an role. 
In the BE-Overview in the instance window I can see that instance has 
an contact.

Would be great if you have an idea, I'm near to delete it all and 
install new :(

Greetings Nina
