Mmm, fine. 

I don't use Exim very much (I have a strange relation with Exim, it's 
there -and I know it is- but I barely notice its presence nor review the 
logs not check what's doing), so I guessed the re-configuration routine 
will ask for the interfaces to use and allows the user to manually define 
them but I can't be sure :-)

Then Exim is right but, how that can be? :-?

sm01@stt008:~$ /sbin/ifconfig lo
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:560 (560.0 B)  TX bytes:560 (560.0 B)

Check you "/etc/hosts" file. You should have this line which enables the 
ipv6 loopback interface:

***
::1     localhost ip6-localhost ip6-loopback
***
