Yes but I don't quite understand why. It's my laptop system and I don't 
really need or want sendmail there. I guess it must be some script 
trying to send email instead of logging to a file.
But how can I find out exactly what is trying to use sendmail (which 
fails and complaints)?

My configuration (8.0-RELEASE-p3):
/etc/rc.conf
    hostname="prime"
    sendmail_enable="NONE"
/etc/hosts
    ::1                     localhost prime
    127.0.0.1               localhost prime
/etc/nsswitch.conf
    hosts: files dns
/etc/periodic.conf
    daily_output="/var/log/dper.log"
    daily_clean_hoststat_enable="NO"
    daily_backup_aliases_enable="NO"
    daily_status_mailq_enable="NO"
    daily_status_include_submit_mailq="NO"
    daily_status_mail_rejects_enable="NO"
    daily_queuerun_enable="NO"
    daily_submit_queuerun="NO"
    daily_status_security_output="/var/log/dsec.log"
    weekly_output="/var/log/wper.log"
    monthly_output="/var/log/mper.log"

It was all fine and quiet for months and started just recently. The only 
change in the system I can think of is that I replaced pf with ipfw. 
Still don't understand what is so urgent that sendmail keeps trying 
every minute.
