Very briefly,
You just need to set up a design rule that specifies this exception
Polygon <-> mounting hole (size/component/hole size) - whatever is
applicable - to get the result you want. I often have trouble thinking
the same way the design-rule dialogues work but persistence and patience
is a good start.
Failing this, a very reliable quick fix is to add a 'layer-specific keep
out' (circle or arc) primitive to ensure these special case clearances
are followed (remember that a net-name can be assigned to such a
primitive where polygons will pour over if the net-name is the same - NO
NET is the best course until you have a handle on this. 99SE help is
helpful on this subject. If you like this option, screw/bolt/mounting
holes can be easily created as proper component footprints with all
these clearance details that save you a lot of repetitive work for
something you often use.
Best regards,
Jim Parr

Hi Folks,
In my board I want to place the Polygon such that it is
drawn at a clearance of let say 100 mils from the mounting holes while
for the rest of the Board it is drawn at the clearance of 15 mils.
How can I accomplish that in 99SE.
Regards,
Adeel Malik
