".../movemail registered but not installed"

[Thomas Apel <thomas.apel@gmx.net>]

What does the following message mean and what can I do against it?

---
Subject: Output of Anacron job `cron.daily'
Date: Tue, 13 Oct 1998 18:51:27 +0200
From: root (Anacron)
To: root

File /usr/lib/emacs/19.34/i386-debian-linux/movemail registered but not
installed
---

I replaced emacs19 with emacs20 a few days ago which is also when these
messages started. I guess emacs19 somehow wasn't removed properly. But
where is movemail registered and how can I unregister it?

TIA,
Thomas
