...as does this. You probably need to reinstall the netbase package,
using --force-confnew or --force-confmiss to force dpkg to reinstall
the configuration file. (--force-confnew will overwrite
/etc/protocols, /etc/rpc, /etc/services, and /etc/init.d/networking,
but it seems unlikely that you'd manually edit these; enough things
depend on netbase that purging and reinstalling it won't work.)
/etc/services contains a mapping from a service name to a TCP or UDP
port number, so things can use names rather than well-known port
numbers. I'd expect programs to contain fallbacks -- even if
/etc/services doesn't contain an entry for "smtp", port 25 is fairly
well-known -- but apparently neither exim nor telnet do.

I get that too; I haven't figured out a good way to disable it yet
(though I haven't looked hard); I'd be happier making logcheck not
send me mail about it, which should be easier to fix. It does seem to
be normal, and an artifact of exim setting up a cron job to
periodically run its outgoing mail queue.
