been there done that. Looking to follow the flow of no MTA. See if
it can be done.
Well, as it has been said, mailx is not an MTA, and it takes an MTA to
transfer mail (even locally, because it crosses privilege boundaries).
In the "old days", /bin/mail was setuid and could directly write
/var/mail, but there were security issues with that and it is no longer
supported (it also caused confusion when you actually had a local MTA
configured to smart-host to a remote server).
If you want to handle mail in any fashion beyond using a client that
sends/receives via network protocols (IMAP/POP3 and SMTP to a remote
server, like mutt or Thunderbird), install an MTA. IIRC, at least
Postfix and Sendmail will work for local mail handling (and not
listening on the network) in a default install, so "yum install <your
preferred MTA>" and you should be set.
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/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.
I did search, and read your post and made responses before starting this
thread.
I can see why the securities boundary issue means that a secure process
with elevated privledges has to do the writing to /var/mail, and mailx
does not run as such. Thus we need a real MTA for this purpose and
choose sendmail or postfix.
