Bug#292191: upgrade changes ownerhsip of /var/spool/exim4

[Marc Lehmann]

Package: exim4
Version: 4.43-4
Severity: critical
Justification: causes serious data loss


I tagged this report as critical because the problem has caused mail to be
lost in the past and would likely result in lost mail in the future.

On every upgrade of the exim4 package, on any of our machines,
/var/spool/exim4 is being chown'ed to Debian-exim4, which causes the spool
files to become inaccessible to exim and causes it not to accept new mail.

The correct user to chown to would be 8:8, as this is what our
exim4-config specifies.

This has been corrected manually a number of times, but it happens
everytime that the exim4 package gets upgraded, and a manual chown is
often forgotten.
