cron using sendmail?

[Konrad Neuwirth]

Dear all, 

I need help again. 

I am probably to blind, but: I have set (via rc.conf) for my system to use postfix instead of sendmail: 

sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

postfix_enable=“YES"

But cron still opens /usr/bin/sendmail: 

  6964 ??  I0Ls     0:00.01 /usr/sbin/sendmail -FCronDaemon -odi -oem -oi -t
  6965 ??  I1Ls     0:00.01 /usr/sbin/sendmail -FCronDaemon -odi -oem -oi -t

What am I missing? Why is it not using the postfix stuff? 

Thank you,
 Konrad
