Yes, I noticed that sshd is started before sendmail, but I didn't know
(properly checked) that setting it to "NONE" is deprecated.  From the
man page we would need to set 4 options to "NO" which is not worth it.

Other possible solution would be to set hostname to $domname.local,
that would make sendmail happy as well.
