Bug#375072: exim4: Wrong file permissions of mailboxes in /var/spool

[Michael Biebl]

Package: exim4
Version: 4.62-1
Severity: important


I intalled etch from the beta2 install cd and configured exim4 to do
local delivery only. After the installation mail delivery to a local
user account failed because the file permission were not set correctly.
This is how it looked on my system after the installation:

pluto:/etc/exim4# ls -la /var/mail/
insgesamt 8
drwxrwsr-x  2 root mail 4096 2006-06-23 05:05 .
drwxr-xr-x 15 root root 4096 2006-06-23 02:36 ..
----------  1 root mail    0 2006-06-01 20:03 Debian-exim
----------  1 root mail    0 2006-06-01 20:09 gdm
----------  1 root mail    0 2006-06-01 20:06 hal
----------  1 root mail    0 2006-06-01 20:04 identd
----------  1 root mail    0 2006-06-01 20:05 messagebus
----------  1 root mail    0 2006-06-01 20:12 michael
----------  1 root mail    0 2006-06-01 20:04 statd

I'm not quite sure if this is a bug of exim or d-i. If the latter please
reassign the bug. 
As a measure of safety though you could check in the exim postinst
script, if the permissions in /var/mail are set correctly and if not
correct them or at least give a warning.

Cheers,
Michael
