Thanks for the reply. I know you are a busy guy and I appreciate the direct 
response.

I did not find an exact situation like that in the documentation, so I took 
that as I was trying to do something unsupported or I was overlooking it.

I did find examples of providing custom messages for reject responses in the 
access(5) documentation. I also found the example in the Linux Email book that 
i mentioned which appears to work as given, so I assumed my syntax was probably 
just off.

Is there a way to accomplish what the Linux Email book mentions? Basically 
restricting use of your domain to your clients/backup MX and using a custom 
response or log message to indicate what rule blocked offenders?

Thanks for your help.
