Re: Loop problem in sending mail to root

The answer is probably in your /etc/mail/aliases file. Do you have
an entry for root in there? If so, it needs to point to a different
user. An entry like the following would cause the error:

root: root

For sendmail, an entry like this would cause the mail to be delivered
locally for the user. With smtpd it results in a mail loop.
