Exim4-Amavisd-new not working after upgrade

[Aart Koelewijn]

This afternoon I upgraded my box from Ubuntu 10.04 to 10.10. I am running 
my own mailserver, exim4, with amavisd-new for spam-checking.

Before the upgrade when I receive a mail I see this in /var/log/exim4/
mainlog:

2010-11-12 13:29:53 1PGslM-0003bF-VZ <= info at arthuus.nl H=bsmtp5.xs4all.nl

Since the upgrade I see:

2010-11-12 18:10:13 1PGx8f-0001uo-2O <= gpsd-users-
bounces at lists.berlios.de H=bsmtp3.xs4all.nl [194.109.127.152] P=esmtp

This are of course different mails used as examples.

I checked the config files for exim4 and amavisd-new but can not find any 
changes. I also checked them against the examples in the docs, but they 
seem ok.

Does anyone have a idea where the problem might be?

(I am lucky to follow this list trough the newsserver, otherwise I would 
have been unable to receive any replies)
