Hi Marc,

I don't think that helps or changes the situation at all.

 . eximstats generates an empty email, rather than either no mail at
   all, or an email that says just: "no mail activity in this
   interval".
 . mail gets an empty pipe and sends a warning to stderr (in a cronjob
   that'll end up going to the same place as before).
   $ sudo /etc/cron.daily/exim4-base
   **** No valid log lines read
   Null message body; hope that's ok

Either eximstats needs to be patched to handle the case of no matching
input lines, or it running it needs to be avoided in that situation.
