"/usr/sbin/sendmail" is also the value defined by _PATH_SENDMAIL in <paths.h> but nothing in-tree seems to use it. Let's not forget nightly.sh's end-of-run mails and whatever else in omnios-userland that expects a working mail transport to be present.

I already said as much on github, but these are why I think OmniOS does
need an MSA+LDA at least.

What happens to the consumers listed above if this happens?

I've been trying to avoid painting this particular bikeshed until it's
at least planned to be built, so I wouldn't draw any conclusions yet.

There's no I can see reason anyone wanting to keep using sendmail
couldn't use a different copy, so I don't consider this a problem.

Where does the milter requirement come from? Per KYSTY I would think
OmniOS should only deliver what it needs to function itself. Are there
milter consumers in -gate or omnios-userland?

If you're asking for opinions on what to do, I don't think keeping
sendmail on life support is worth it, which removes option 1. Since
there are MSA/LDA consumers, option 2 isn't feasible either. That leaves
only option 3, unless "do nothing" is an option.
