dma accepts mail from a local Mail User Agent (MUA) and delivers it
locally or to a smarthost for delivery. dma does not accept inbound
mail (i.e., it does not listen on port 25) and is not intended to
provide the same functionality as a full MTA like postfix or sendmail.
It is intended for use cases such as delivering cron(8) mail. which
is the default configuration and usage of sendmail in the default
setup of the base system.
In order to switch the default from sendmail to dma, we teach
mailwrapper to fallback on dma directly if the mailer.conf file cannot
be opened.
We install by default a mailer.conf file which points at dma
We install a mailer.conf file for sendmail in the examples.

This would allow interested parties to do experimental runs with an
environment set appropriately to raise all the warnings throughout the
build; e.g. env WARNS=6 NO_WERROR=yes buildworld.
Not currently touching the numerous instances in ^/tools.
MFC after: 1 week
Most important change being:
dma - Fix security hole (#46)
Affecting DragonFly 4.6 and earlier, Matt Dillon fixed this in base after
finding out from BSDNow Episode 152. Comments following were from his commit
which explains better than I. Just taking his change and putting it here as well.
* dma makes an age-old mistake of not properly checking whether a file
owned by a user is a symlink or not, a bug which the original mail.local
also had.
* Add O_NOFOLLOW to disallow symlinks.
Thanks-to: BSDNow Episode 152, made me dive dma to check when they talked
about the mail.local bug.
MFC After: 2 days
for the CONFS issue with dma.conf and ppp.conf.
Thank you very much to Bryan Drewery for looking into the
problem and providing this fix.

The 'CONFS' entries in share/mk/bsd.confs.mk explicitly check
for the 'installconfig', but does not behave properly with the
'distribute' target.
This seems to be related to the previously-reported issues
with files within /etc in the past.

These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.
Currently rescue/rescue and sys/modules are still not connected.

Simplifying maintainance and options (only one place to deal with MK_DMAGENT)
This also makes packaging base less intrusive by getting a single point where
to add tags.
It is a small and lightweight Mail Transport Agent.
It accepts mails from locally installed Mail User Agents (MUA) and delivers the
mails either locally or to a remote destination. Remote delivery includes
several features like TLS/SSL support, SMTP authentication and NULLCLIENT.
Make dma conditional to new WITHOUT_DMA option and make it respect WITHOUT_MAIL
