[horde] Missing "Junk" folder on activesync devices after SPAM configuration

[sascha at schmidt.ps]

Hi,

I'm faced with the problem that the "Junk" folder disappears when the  
Horde Spam configuration has been done. After removing this  
configuration (within backends.local.php and preferences) the Junk  
folder appears again over activesync.

I can reproduce this behaviour every time I add Spam (report) settings.

The Junk (really name of this folder) folder is need by iOS devices to  
use the function "Move to spam". Without this folder moving spam isn't  
possible anymore with one click.

Hoping for hints...
