Package: postfix
Version: 2.2.4-1.0.1
Severity: normal
Trying to run "sudo newaliases" fails with a permission denied error,
despite the destination file, /etc/aliases.db, being owned by root and
being user writeable.

A system call trace shows it setting the effective user id to 500 (my
original user id) before attempting to open the aliases database file.
I don't see why it should do this at all.
