The IronWebMail product from CipherTrust proxies webmail connections and
scans the stream for signature matches on know bad traffic.  It will
block attacks before they're passed to the internal server.  For OWA
specifically it has the ability to do session length enforcement,
time-out enforcement, and real secure log-off (which OWA was totally
lacking prior to 2K3).

It works with any webmail product (or any HTTP traffic, for that
matter), but the extended features around session management are for
OWA-only.

There are other commercial products available that also do AV and
content scanning on webmail traffic, although I'm not aware of the
performance implications of such a setup.
