Yes, I did this, after eximconfig:

   sudo update-inetd --disable smtp

Yes, I know that I can run any number of MTA's, including exim, qmail,
&c.  However, my point is that there are boxen on which *only* local,
system mail is appropriate.  Mine is one of those.

In this case, what is the Debian way to run an absolutely minimum MTA,
the smallest possible footprint, least likely setup to disrupt apt-get'd
applications, and as secure as possible.

So far, I have not seen any response address this.  Or, am I missing
