I was under the same impression, hence my original thread:

  <https://lists.fedoraproject.org/pipermail/users/2013-December/443441.html>

However I was told (by Frank) that it is possible using mailx.

  <https://lists.fedoraproject.org/pipermail/users/2013-December/444265.html>
  <https://lists.fedoraproject.org/pipermail/users/2013-December/444304.html>

So now I'm completely lost as to what is possible and what is not.  For
now I have sendmail installed, but if possible I would like to remove
that (at least on my laptop).

Hope that makes sense.  And thanks for any explanations.

Cheers,
