Bounce mail Bounced

I am trying to set up a mail server. Everything works ok on my end, but I am starting to get this type of message. Should I do something or is this a good thing?  I don't want to help generate/pass spam!
(mail.jamesxxx.com is my domain and 65.69.184.xxx is my ip)

Hi. This is the qmail-send program at mail.jamesxxxx.com.
I tried to deliver a bounce message to this address, but the bounce bounced!

<jeffery@65.69.184.xxx>:
Sorry. Although I'm listed as a best-preference MX or A for that host,
it isn't in my control/locals file, so I don't treat it as local. (#5.4.6)

--- Below this line is the original bounce.
