The default exim.conf seems good enough for delivering local e-mail
(not sure about if it is secure enough). However I have found the
following line does not allow mails to arrive to the root:

never_users = root

The line above prevents me to send mails to the root (and I suppose it
also prevents local process to send mails notifying about errors). I
have an additional doubt:

3) Is it dangerous to allow mails to be sent to the root? (the default
fedora/sendmail configuration seems to permit this)
Anyway, creating a .forward file in /root allowed me to forward the
e-mails to another user, and then I can keep the default never_users
setting, but I wondered why it is set this way
