I too configure postfix to handle local mail that does not get
outside my home network. But postfix does not come as the default
MTA, sendmail does!

So I would have expected either a release note on how to
configure sendmail to allow local mail delivery (ie cron/anacron/mail)
to function smoothly or a default configuration that already
included this setup. 
Most newbies will end up being on 'localhost.localdomain'.

The default is rather sloppy in my opinion.
