The periodic script does its own output using this:

output_pipe()
{
     # Where's our output going ?
     eval output=\$${1##*/}_output
     case "$output" in
     /*) pipe="cat >>$output";;
     "") pipe=cat;;
     *)  pipe="mail -E -s '$host ${2}${2:+ }${1##*/} run output' $output";;
     esac
     eval $pipe
}

You need to override the various *_output variables periodic uses in 
/etc/periodic.conf. See my earlier mail on the subject.
