ACL Permission Question

[List Account <listac@xxxxxxxxxxxxxxxx>]

Hi,

I wonder wether it is possible with XFS and ACLs to allow a group to 
write (copy, ...) a file into a folder (and subfolders thereof), but not 
delete files out of the folder(s). Basically, one may just put in the 
bucket, but not take out anything.

I have played a bit with ACLs, but havent managed yet. Still, I am far 
away from really work with it "by heart.", so maybe I lack some basic 
understanding.

Regards
