A little update report. After the setup of dma went so smoothly on my Arch
installations, I wanted to recreate it on my Gentoo-based NAS over the
weekend:

- cloned the dma repo¹ and installed everything
- removed everything from /var/spool/mail and any leftover queues for a
  clean start
- changed the sendmail path in fcron.conf from usr/bin to usr/local/bin
- had to amend /etc/mailutils.conf, because it sets up the root mailbox as
  a maildir called .maildir (according to the comment, that is Gentoo-
  specific). So I just commented out that block to (hopefully) get GNU
  maildir default behavior

Now I finally get mails from cron et al on my NAS and can read them with
mail or mutt. I can sleep better now, knowing that it will monitor its four
6 TB disks and notify me at the first sign of trouble, including “there is
new mail” on the console. \o/

There is one last niggle: after I read a message with the mail tool, it
saves those messages in /root/mbox. It does not do this on Arch, but keeps
them in /var/spool/mail/root instead. So far I haven’t found out why it does
that and where that might be configured. Perhaps some leftover config from
previous experiments with different mail packages.
