I downloaded the latest version of BLAT and will take a look at it.

Question:
How do you prevent users from using it as an Anonymous emailer?
We have users from DUNCE to Phd.
If I set this up I'm afraid some of the smarter users will start using it as an Anonymous emailer since we already sit behind a firewall that makes an email hard to track down were it not for the name.
If they add a bogus name won't it be pretty hard to track down who or where it really came from?
