<P>Thanks for the response, I removed dnl from the line referenced below and rebuilt the sendmail.cf and it is working now. I am curious to know if anyone is aware of any security issues involved in allowing unresolvable domains to send mail? What is the preferred setting for most people?
<P>Thanks again for the response.
