Eric,
You are correct in the fact that the host file did not fix the
issue. Neither did adding the IP to the tcp.smtp file change. Like you
suggested, fixing the problem at the source is preferable.
Can you suggest what needs to be changed in the sendmail.cf file, or should
I be changing to postfix, as suggested by some others?
Please let me know, and keep those suggestions coming.
Cheers

Subject: [qmailtoaster] Re: Server Mail
I'd like to know if this works, but I don't expect it will.
I believe that chkuser is not finding an MX record for the
backup.mydomain.com domain, and this cannot be specified in the hosts
file. An MX record for backup.mydomain.dom would need to be added to the
authoritative DNS for the mydomain.com domain. While this would fix the
problem, I don't think it's the best solution.
Fixing the problem at its source is preferable. (more on that elsewhere)
