This error is caused by the "From" address is an unknown

domain to the recipient.



The root of this is that sendmail cannot find the FQDN for the box.



Make sure /etc/hosts has the correct info for the machine:

10.5.4.3 joemachine.realdomain.com joemachine



Also make sure resolv.conf has the domainname set and that the

machinen is properly entered into DNS.
