I have never seen a linux system with libc6 that did not have nsswitch. I'm
fairly sure your system should have it.
I'm running debian and I do have /etc/nsswitch as follows:
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
passwd: ldap files
group: ldap files
shadow: ldap files
hosts: files dns
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis
for passwd, group and shadow, yours should probably say compat if you wish
to copy my file. I do use LDAP for user information and it falls back to
files.

Notice you are running as root here. I'm willing to bet that the
permissions on /etc/group are not allowing it to be read by exim since exim
does not run as root. Do ls -l /etc/group and past that line.
My /etc/group:
-rw-r--r-- 1 root root 599 May 27 20:49 /etc/group
Also, passwd should have the same permissions.
If you have /etc/shadow, it should not be world readable.
