[Mailman-Users] question regarding cron

[Alex at Idoia]

Hello,

I have installed mailman on my debian woody. I have checked recently my 
/var/log/auth.log and they are poluated by a cron that is being 
executed by mailman every minutes of every day:
# */5 * * * *   list    [ -x /usr/bin/python -a -f 
/usr/lib/mailman/cron/gate_news ] && /usr/bin/python 
/usr/lib/mailman/cron/gate_news
* * * * *       list    [ -x /usr/bin/python -a -f 
/usr/lib/mailman/cron/qrunner ] && /usr/bin/python 
/usr/lib/mailman/cron/qrunner
Can you explain me this ?
Is this really necessary ?
Can we prevent it from being printed in my /auth.log ?
Thanks alot
Alex
