some process did a touch(1) or otherwise changing
$ stat /etc/exim4/update-exim4.conf.conf

causing alarm bells to ring on my homebrew security system.

Please don't "touch" files for no good reason. Thanks.

P.S., In fact, looking at that second in /var/log/dpkg.log shows:

(Plus I bet it is a policy violation.)
