How does the new Exchange 2003 SP1 OWA attachment registry entry 
'KnownContentTypes' work with the other registry entries for blocking 
attachments in OWA.
Does this new entry take precedent, or is it cumulative.

Also will the OWA Web Admin be changed to handle this?

MS KB 873138 and 555001.

Question is if I only allow types of .txt and .doc in the level1 and
level2 categories, would it stop an executable file being attached.? As
one can rename the executable with an extension of .txt and OWA accepts
it as an attachment.
