Nobody interested in the traces?

Here's how often I get the errors:
$ zgrep -h PEEK /var/log/syslog* | awk '{print $1 " " $2}' | sort|uniq -c
     18 Mar 1
      9 Mar 2
     23 Mar 3
     25 Mar 4
     30 Mar 5

That's with about 5 mail fetches per hour (some of which will be empty).
On Mar 2 I had some fetches disabled for debugging.

Cheers,
