It looks like GNUMail is using a subclass of NSTableView in the mail
window. This table is the source of the operation. What I found out so
far is that the target of the operation (outline view) in the method -
outlineView:validateDrop:proposedItem:proposedChildIndex: receives
NSDragOperationNone in the NSDraggingInfo object ([info
draggingSourceOperationMask]), no matter which modifier I press down.

Cheers,
Andreas
