Hello. I have a problem. When I create folder with Thunderbird client, the permision will be 777. And now cannot delete folder under Thunderbird client, because the permssion must be 700, not 777. Why the permission 777, when create folder? What setting can be used to change to the normal permission?
See https://doc.dovecot.org/3.0/admin_manual/filesystem_permission/ maybe the permission of the mailbox root is wrong for that mailbox.
Thx. The settings is good I see, but somebody change /var/vmail/accountname permission to 777, and now the new subfolders inherit from it. Thx for your help!
