I'm using docker to provide an mta.
But it's broken apt because it won't let me install packages that need an mta (e.g. bsd-mailx).
For individual packages I can force it; download the package and use dpkg -f -i package.deb but that still leaves apt fretting about an unresolved dependency, which prevents me installing other packages that are nothing to do with the MTA.
e.g.
$ apt install silversearcher-ag

The following packages have unmet dependencies:
bsd-mailx : Depends: default-mta or
mail-transport-agent
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Is there a way to tell it that there is a mail-transport-agent package installed? (I'm on Debian 9)
