Look at the line above. You are running sendmail with a vanilla
localhost.cf, _not_ sendmail.cf.

Read "Sendmail" section of "man afterboot". You were supposed to do this
after install. And read the comment in /etc/rc.conf exactly above the
sendmail line you mentioned at the beginning. It says:

# For normal use: "-L sm-mta -bd -q30m"
sendmail_flags="-L sm-mta -C/etc/mail/localhost.cf -bd -q30m"
