I have been asked to redirect the mail for one domain on a RAQ 4 to an
exchange server.

I 've set up what i believe are the correct DNS settings:

   mydomain.com  -> IP ADDRESS of web server

   www.mydomain.com  -> IP ADDRESS of web server

   mail.mydomain.com -> IP ADDRESS of exchange Server

   www.mydomain.com -> mail.mydomain.com


When I send an email to someone at that domain through our mail server on
same domain i get the message:

   Host unknown (Name server: mydomain.com: no data known)

When someone send mail externally the following mesage is returned:

   A message that you sent could not be delivered to one or more of its
   recipients. This is a permanent error. The following address(es) failed:

  person@xxxxxxxxxxxx
    SMTP error from remote mailer after RCPT
  TO:<person@xxxxxxxxxxxx>:
    host mydomain.com[IP ADDRESS]: 550 5.7.1
  person@xxxxxxxxxxxxxxx Relaying denied.  Please check your mail first.


Has anyone got any ideas why the above would not work?

Any ideas/help would be much appreciated.
