It's not fetchmail that is sending those emails, but cron. Any output
from a cron job is 'captured' by cron and sent to the owner of the cron
job.
If you redirect the standard output from fetchmail to /dev/null (by
adding "> /dev/null" to the end of the fetchmail command) no output from
fetchmail is seen by cron and no email will be sent.
