Notice that such entry will be ignored when DISPLAY is not set due to
specified "test" property. You need to pass X socket and pass or set
DISPLAY environment to you "headless" container.
Also, note that mailcap.el contains `mailcap-mailcap-entry-passes-test'
and that function is ... interesting. At least, it should work fine with
the test above, but only very limited number of tests appears to be
supported.
Best,
