Passing along as Postfix is now default MTA for Devuan/Debian.
Untested by this reporter. (Personally, I still like Exim4.)

Subject: [NBLUG/talk] Check default_transport if you can't send email
    through Postfix

If you initially tell debconf that you want local mail delivery only, it
helpfully configures Postfix with:

default_transport = error

Postfix will bounce emails with code 5.0.0 and absolutely no further
explanation. Nothing in the bounce notification email, nothing in the logs,
just nothing.

I spent two days figuring that out.
