I have a CentOS server. It has sendmail installed but not used for a mail server. I forwarded the root email to another email address. However, I keep getting errors in maillog:
Dec 6 08:49:16 server1 sm-msp-queue[16191]: qB6601et005433: to=root, ctladdr=root (0/0), delay=08:49:15, xdelay=00:00:00, mailer=relay, pri=883224, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: [127.0.0.1]: No route to host

In the forwarded email address, I received notification "it can't deliver email to [email protected].
subdoamin.example.com does have a MX record, and I do not want to add one.
Is there any configuration that I can change to prevent this error? I want all emails to the root to be forwarded to the forward address.
