From the technical FAQ at
http://www.e-smith.org:
Why am I receiving emails with Subject: /etc/startmail, with only dots in the body of the message?
These harmless messages are a progress indicator that fetchmail is fetching messages.
In order to stop the cron messages being sent to admin, you'll need to set the Verbosity property of fetchmail to --silent. You can do this by entering the following commands: (while logged into the e-smith server as root)
/sbin/e-smith/db configuration setprop fetchmail Verbosity "--silent"
/sbin/e-smith/signal-event email-update
Sorry for my mistake, it wa a long time ago when I 'fixed' this, so it's not a contributed rpm but a known issue reported in the T-Faq.
