Hi all! I've got quite simple question from dovecot's upstream: Why do we have rw access on mails for mail group? Why /var/mail/<username> files have 0660 <username>:mail permissions instead of 0600 permissions? The fact is, I don't know the answer and I'd appreciate your help. Some facts: distro | group | perm ---------+-------+--------- Fedora | mail | 0660 Ubuntu | mail | 0600 openSuSE | users | 0600 (user is member of users group) debian 4.0 | mail | 0660 (Note: This is result of my own investigations on installed systems or livecds, I don't know if any installed system had changed settings.) Interesting thing is, that when new user is added to the system, useradd creates /var/mail/<username> file with <username>:mail 0660 permissions, but when you delete this file and the user gets new email, this file will be autocreated with 0600 permissions (still <username>:group owned) and it seems everything still works. useradd command comes from shadow-utils and fedora contains no patch changing permissions to 0660. The most important question is: Is there anything that requires these files can be read and written by mail group? If you have any info regarding this, please share.
