Exim4 error - group mail not found

[Markus Meyer <markusmeyer1@web.de>]

Hi folks,

since two days my Exim4 won't start allthough I can't remember making any
changes to it's config. It's running as relay to forward my mails I write
with Mutt to my Mail-Provider. My system is a Debian-Unstable. When I start
Exim the folowing comes out:
Starting MTA: 2004-07-10 09:56:25 Exim configuration error in line 266
of /var/lib/exim4/config.autogenerated.tmp:
  group mail was not found
Invalid new configfile /var/lib/exim4/config.autogenerated.tmp
not installing /var/lib/exim4/config.autogenerated.tmp to 
/var/lib/exim4/config.autogenerated

Line 266 only says group = mail. But the group mail does exist my system
(/etc/group: mail:x:8:) and the mail-dir also has the correct perms:
[butterblume 16] apt > la /var/mail
