[fetchmail]supress errors in log

[Paul Goodyear]

-- /etc/crontab
*/1   *   *   *   *   user1   /usr/local/bin/fetchmail --silent --syslog

when fetchmal runs all logs about "no emails on server", and all
"Server CommonName mismatch: localhost.localdomain !=3D
mail.myserver.net" are not sent to the user which is great.

But when the internet dies, or not available the user is still swamped
emails containing:

"fetchmail: another foreground fetchmail is running at <uid>"

Can these be stopped also?

Thanks.
