Add a CNAME record to your DNS.
Mail delivery is supposed to ignore CNAME records. Perhaps you meant
to say an MX record. But either way, the OP's question is still not
answered -- where is the recipient address configured?
My guess would be "in the system's MTA". I'm guessing the SMART tools
are simply sending to "root" with no domain, and relying on the system's
MTA to fill in the recipient domain. I'm guessing this MTA is not
configured properly.
The OP should verify this by running something like:
echo test | mailx -s test root
And see how the message headers get written, and where the message goes.
If it turns out my guesses are right and the MTA is misconfigured, then
we'll know the next steps.
If it turns out my guesses are wrong, and the MTA is fine, then we'll
have to figure out how these SMART tools are configured.
