Which makes no sense, since you're using postfix -- postfix does not use
that directory.  It sounds to me like possibly your
/etc/mail/mailer.conf (used by mailwrapper) is still pointing to the
Sendmail (non-postfix) binaries.

You should be using these values in rc.conf:

# We use postfix
postfix_enable="yes"
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

And these values in periodic.conf:

# We use postfix
daily_clean_hoststat_enable="NO"
daily_status_mail_rejects_enable="NO"
daily_status_include_submit_mailq="NO"
daily_submit_queuerun="NO"

And these values in /etc/mail/mailer.conf:

sendmail	/usr/local/sbin/sendmail
send-mail	/usr/local/sbin/sendmail
mailq		/usr/local/sbin/sendmail
newaliases	/usr/local/sbin/sendmail

If you *really* want to turn off daily/weekly/monthly mails -- which I
strongly DO NOT recommend you do, for MANY reasons -- you should look at
/etc/defaults/periodic.conf for all of the values you can tune.  DO NOT
edit that file -- use /etc/periodic.conf instead.
