+I do not use emails on my FreeBSD machine so I did not bother setting it up. But it runs at startup and apparently prevents other services from starting till it finishes its job (I cannot ssh into this machine till sendmail decides it has had enough and stops).
+
+<!--more-->
+
+Change these lines to `/etc/mail/mailer.conf` to 
+```
+sendmail   /usr/bin/true
+mailq      /usr/bin/true
+newaliases /usr/bin/true
+hoststat   /usr/bin/true
+purgestat  /usr/bin/true 
+```
+And in `/etc/periodic/periodic.conf` to 
+```
+# disable sendmail (mailqueue) cleanups:
+daily_clean_hoststat_enable="NO"
+daily_status_mail_rejects_enable="NO"
+daily_status_mailq_enable="NO"
+daily_submit_queuerun="NO"
+
+# disable periodic's emailing by logging!
+daily_output=/var/log/daily.log
+weekly_output=/var/log/weekly.log
+monthly_output=/var/log/monthly.log
+
+# put these into the log, instead of trying to mail them
+daily_status_security_inline="YES"
+weekly_status_security_inline="YES"
+monthly_status_security_inline="YES"
+```
+And in `/etc/rc.conf` to 
+```
+# disable sendmail
+sendmail_enable="NO"
+sendmail_submit_enable="NO"
+sendmail_msp_queue_enable="NO"
+sendmail_outbound_enable="NO"
+
+# don't allow cron to mail
+cron_flags="-m ''"
+```
