I'll fix lnfs for you, its a whole line to type but I'll go out of my way
just this once...

You can't override dns by changing ndb unless you own the domain, i.e.,
have a soa= in the record for the domain root.

A better solution might be to, as collyer suggests, change your rwrite rules
so that
you redirect the message to where you really would like it to go.
