In general +1. I personaly use msmtp for mail delivery since I don't want to
mess with a full MTA configuration. If we enable DMA by default, we also should
update the existing documentation. I recently discovered that following rc.conf
values are needed for local delivery of status e-mails from rc-scripts.
sendmail_submit_enable="YES"
sendmail_msp_queue_enable="YES"

But since we have DMA already in base, the switch would be more then welcome,
to move to a BSD-licsended, simple to use solution.
