Sendmail in TruCluster 5.1 - reverse checking sender address

I have problem with sendmail in TruCluster 5.1 (PK5).

I can't send mails as root to external who will do reverse checking of
sender's address. The problem is we have a valid domain name but the
cluster doesn't have a fully qualified host-name (cluster alias). So the
sender address is not valid.

For example, we registered a domain name foo.com
We have a cluster whose alias is cluster_alias.foo.com.
The cluster has 2 nodes: alpha1.foo.com and alpha2.foo.com
They are all not fully qualified.

Now mails sent out as root from any nodes of the cluster will have address
like: root_at_cluster_alias.foo.com

I have modified the sendmail.cf in both nodes:
from "CWalpha1.foo.com" to "CWfoo.com" and
from "CNroot postmaster news uucp mailer-daemon rdist nobody daemon pop"
to "CNpostmaster news uucp mailer-daemon rdist nobody daemon pop"
And restart sendmail daemons on both nodes.

But mails sent out as root from any nodes of the cluster still have address
like: root_at_cluster_alias.foo.com

I did the same changes on a non-cluster 5.1 box and it works.
The same changes don't work on TruCluster 5.1 (PK3) either.

Any help would be very appreciated.
