I tested with the latest files on CVS (this morning), the error is
always here.
To reproduce the problem:
- edit crontab root
- set a fake cronjob which print anything: */1 * * * * ls /
- set a root alias (/etc/mail/aliases) to an other mail (root:
yourem...@yourprovider.com)
And wait to receive the mail... See the header (I replaced my full
hostname by sub.domain.net, and the root alias by yourem...@free.fr)

As you can see, the problem is the "From" field. There is no hostname
here. So, a MUA can't answer to it.
If you send a mail with : echo "hello world" | mail
youru...@yourprovider.com, no problem. The problem is *only* when a mail
is sent from and by a crontab with OpenSMTPd (no problems with Sendmail
or Postfix).
