Hi,
Yes! After permission changing everything works properly for only one time. After only one modification for a message I lose bar.
Looking permissions in quarantine folder I see all messages with -rwxrwx--- permissions and touched message is -rw-------only.
After one attmpt to solve this problem (changing in mailscanner configuration masks from 0600 to 0770) everything works fine everytime.
Sorry for my bad and poor english!
