That's by design, believe it or not.  'root' is a member of class E --
Exposed Users -- whoese e-mail addresses won't be rewritten by
genericstable processing or the like.

On your mail host, you need to add the names of all of the hosts you
provide mail service for to the /etc/mail/local-host-names file, one
per line.

Not relevant to your current problem, but you've got your MX pointed
to a CNAME.  That's bad karma and not permitted by the DNS standards.
You should make mail.kibserv.org into an A record like so:

mail.kibserv.org.	1H IN A	10.0.0.8
stan.kibserv.org.	1H IN A	10.0.0.8

and similarly, provide PTR records for both names:

$ORIGIN 0.0.10.in-addr.arpa.

8	1H	IN	PTR	mail.kibserv.org.
			PTR	stan.kibserv.org.

	Cheers,
