tklbam and configuration issue

Hello -

I have two general configuration questions.

1.  tklbam is sending an email to root at <my domain>, how can I configure it to send to a different account?

2.  Where do I set the DNS name of an appliance so that it is recognized?  It seems to work sometimes but not others.  I looked for documentation on this and couldn't find it.  Example: one of my Wordpress installations only has the IP in the grayed-out box.  Others have the domain name.

Thanks!
