Hi, I have a user called archive that gets a BCC of all incoming/outgoing
email. I would like to have the email in the new/cur directories setup to be
read only, is there a way to do this in dovecot 2.0.8. I know you can set
the umask in the dovecot config but I believe this is a global setting.

subfolders with the name 'Untitled Folder'. When they try to rename these
