I cannot speak on the specifics as (with exim4 and now DMA) my box's
MTA (desktop Devuan) is absolutely transparent to me.

Sitting in a corner of my desktop there is a tiny, simple and very
effective application from eons ago (coolmail 1.3-12) watching my
inbox mail file and lets me know when I have new mail from any
applications that have been configured to send mail to the system
administrator.

What I can say is that the botched exim4 upgrade* left me without the
notifications I need to receive when something is *not* working as
expected with all that that entails, even in a simple single user
desktop system.

Purging (with extreme prejudice) all traces of exim4 and installing
DMA instantly made things normal again and it has been so from that
day on.

* tl;tr:
It seems that it is *not* a bug if you update a package, choose the
default and recommended action offered by the dpkg installer and as a
result break an essential part of your Linux system.
eg: your system's MTA.

And the absurd reply from the devs when I attempted to file a bug:

My box (XFCE4) runs the cron-daemon which is needed by timeshift, so
I guess it is.
