new problem

[Walter Ulmke]

1) my inbox is "Posteingang". should I officially declare it somewhere?

I now get the following error messages:

Also, when I start Thunderbird I get the following error message:

"der aktuelle Vorgang in "Posteingang" ist fehlgeschlagen. Der Server 
des Kontos antwortete (Serverbug) Internal error ocurred. Refer to 
server log

WHERE IS THE SERVER LOG?
