Well, .forward and Procmail clearly pre-date 1999.  The claim has to
be more specific.

The "claims" section begins,

So it appears to be limited to an idea involving DNS.  The other claims
all relate to claim 1.

This still looks like an attempt to patent an idea rather than a device,
so it might be weak.  But imagine the dollars to be spent on lawyers to
establish that.
