You should use src.conf(5) and set WITHOUT_SENDMAIL=yes to avoid
building sendmail nowadays.

Postfix normally (when installed from ports) installs a "fake"
sendmail binary in /usr/local/bin. So mailer.conf should contain the
following:

#
# Execute the Postfix sendmail program, named /usr/local/sbin/sendmail
#
sendmail	/usr/local/sbin/sendmail
send-mail	/usr/local/sbin/sendmail
mailq		/usr/local/sbin/sendmail
newaliases	/usr/local/sbin/sendmail

and rc.conf should have:

sendmail_enable="NONE"
