DragonFly Mail Agent
test mail
mail -v -s testmail <email@example.com> < /etc/motd
update permissions
If you get an error like sendmail: can not open auth file '/etc/dma/auth.conf': Permission denied
then you need to fix permissions like so:
chmod 640 /etc/dma/auth.conf doas chgrp mail /etc/dma/auth.conf
