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.

The Dragonfy Mail Agent (dma) can be used with mailwrapper as a
replacement for sendmail(8)
Even if mailwrapper and sendmail are disabled from the build but
dma is not create all the expect symlinks on mailwrapper and make
mailwrapper a symlink to dma, the same way it was done before when
mailwrapper is disabled by sendmail was not.
Discussed with: emaste
When WITHOUT_SENDMAIL is set, we end up with two different mailer.conf that
conflict, and hilarity ensues. There's currently three different places that
we might install mailer.conf:
- ^/etc/Makefile (package=runtime, contingent on MK_MAIL != no)
- ^/libexec/dma/dmagent/Makefile (package=dma, contingent on MK_SENDMAIL !=
no)
- ^/usr.sbin/mailwrapper/Makefile (package=utilities, contingent on
not-installed)
The mailwrapper installation will effectively never happen because the ^/etc
one will first.
This patch simplifies the whole situation; remove the ^/etc/Makefile version
and install it primarily in mailwrapper if MK_MAILWRAPPER != "no". The
scenarios covered in mailwrapper are:
- sendmail(8) is installed, dma(8) may or may not be installed
- neither sendmail(8) nor dma(8) is installed
In the first scenario, sendmail(8) is dominant so we can go ahead and
install the version in ^/etc/mail. In the unlisted scenario, sendmail(8) is
not installed but dma(8) is, we'll let ^/libexec/dma/dmagent do the
installation. In the second listed scenario, we still want to install an
example mailer.conf so just install the base sendmail(8) version.

There has been some fallout from the change. The change itself was not valueable
enough to spend time investigating the corner cases, let's just back it out.

This is something I thought I committed MONTHS ago, but it appears
that I fatfingered it and made a local commit.

BINOWN isn't quite right for this, but it's not really worth creating
a MAILOWN for this.
