We're currently changing the way we're backing up our mail-system.
The backup user by policy has maximally limited permissions. I.e. has
read-only rights to the files it backups.
What i need to do is to make it a part of the vmail group, or change the
vmail group to another group which includes backup. Next I need to give
this group read access to the files.
Here is were I struggle with Postfix. Is this really by design
impossible? I would argue that this breaks the unix permission model,
and will force me to give more rights to the backup user, and lower my
level of security.
Why do I have to that? Or can I control the umask behaviour?
