This is because sendmail nows runs 2 queues, to avoid running suid:
local mails are put in /var/spool/clientmqueue and sent via SMTP to localhost,
where another sendmail, running with root privs, will handle it and deliver
locally or to another MTA. So you need both sendmail=YES and smmsp=YES in
/etc/rc.conf. With a default config sendmail should only listen on
It's still possible to run sendmail suid root and get rid of the network
daemon completely, but I've never done it.
For a nullclient config, just link /etc/mail/ to /etc/mail/
and all will work without a local listening daemon, without a suid-root
