Solution:
This is a two part solution. First I changed my /etc/hosts file by adding
bison to the local host line, which now reads:
127.0.0.1 bison localhost.localdomain localhost
I then restarted named, network, and sendmail (in this order, although not
sure all of this was entirely necessary). This resulted in releasing a
flood of emails from the spool that had been sent from the Arkeia backup
software to jboyce@(protected) (Arkeia had been set up to send
directly to me instead of to root, although this has been changed now.)
Although I was still seeing error messages for emails that were being
directed to root@(protected)
The second part of the solution was to change my /etc/aliases file by
changing the line that redirects roots email. It was initially being
directed to my network account user name (jeffb). It now reads as:
root: jboyce@(protected)
I then re-ran the newaliases macro and then restarted sendmail. Now I
receive the logwatch files that are sent to root daily.
For mail that had been accumulating in /var/spool/mail/root I manually
forwarded this file to my email account to review the history. Thanks for
all the assistance that everyone provided.
